-# Note [Disable automatic stripping]
-# Disabling automatic stripping for a few reasons:
-# - portage's attempt to strip breaks non-native binaries at least on
-# arm: bug #697428
-# - portage's attempt to strip libpthread.so.0 breaks gdb thread
-# enumeration: bug #697910. This is quite subtle:
-# * gdb uses glibc's libthread_db-1.0.so to enumerate threads.
-# * libthread_db-1.0.so needs access to libpthread.so.0 local symbols
-# via 'ps_pglobal_lookup' symbol defined in gdb.
-# * 'ps_pglobal_lookup' uses '.symtab' section table to resolve all
-# known symbols in 'libpthread.so.0'. Specifically 'nptl_version'
-# (unexported) is used to sanity check compatibility before enabling
-# debugging.
-# Also see https://sourceware.org/gdb/wiki/FAQ#GDB_does_not_see_any_threads_besides_the_one_in_which_crash_occurred.3B_or_SIGTRAP_kills_my_program_when_I_set_a_breakpoint
-# * normal 'strip' command trims '.symtab'
-# Thus our main goal here is to prevent 'libpthread.so.0' from
-# losing it's '.symtab' entries.
-# As Gentoo's strip does not allow us to pass less aggressive stripping
-# options and does not check the machine target we disable stripping
-# entirely.

-# Note [Disable automatic stripping]
-# Disabling automatic stripping for a few reasons:
-# - portage's attempt to strip breaks non-native binaries at least on
-# arm: bug #697428
-# - portage's attempt to strip libpthread.so.0 breaks gdb thread
-# enumeration: bug #697910. This is quite subtle:
-# * gdb uses glibc's libthread_db-1.0.so to enumerate threads.
-# * libthread_db-1.0.so needs access to libpthread.so.0 local symbols
-# via 'ps_pglobal_lookup' symbol defined in gdb.
-# * 'ps_pglobal_lookup' uses '.symtab' section table to resolve all
-# known symbols in 'libpthread.so.0'. Specifically 'nptl_version'
-# (unexported) is used to sanity check compatibility before enabling
-# debugging.
-# Also see https://sourceware.org/gdb/wiki/FAQ#GDB_does_not_see_any_threads_besides_the_one_in_which_crash_occurred.3B_or_SIGTRAP_kills_my_program_when_I_set_a_breakpoint
-# * normal 'strip' command trims '.symtab'
-# Thus our main goal here is to prevent 'libpthread.so.0' from
-# losing it's '.symtab' entries.
-# As Gentoo's strip does not allow us to pass less aggressive stripping
-# options and does not check the machine target we disable stripping
-# entirely.

-# Note [Disable automatic stripping]
-# Disabling automatic stripping for a few reasons:
-# - portage's attempt to strip breaks non-native binaries at least on
-# arm: bug #697428
-# - portage's attempt to strip libpthread.so.0 breaks gdb thread
-# enumeration: bug #697910. This is quite subtle:
-# * gdb uses glibc's libthread_db-1.0.so to enumerate threads.
-# * libthread_db-1.0.so needs access to libpthread.so.0 local symbols
-# via 'ps_pglobal_lookup' symbol defined in gdb.
-# * 'ps_pglobal_lookup' uses '.symtab' section table to resolve all
-# known symbols in 'libpthread.so.0'. Specifically 'nptl_version'
-# (unexported) is used to sanity check compatibility before enabling
-# debugging.
-# Also see https://sourceware.org/gdb/wiki/FAQ#GDB_does_not_see_any_threads_besides_the_one_in_which_crash_occurred.3B_or_SIGTRAP_kills_my_program_when_I_set_a_breakpoint
-# * normal 'strip' command trims '.symtab'
-# Thus our main goal here is to prevent 'libpthread.so.0' from
-# losing it's '.symtab' entries.
-# As Gentoo's strip does not allow us to pass less aggressive stripping
-# options and does not check the machine target we disable stripping
-# entirely.

-# Note [Disable automatic stripping]
-# Disabling automatic stripping for a few reasons:
-# - portage's attempt to strip breaks non-native binaries at least on
-# arm: bug #697428
-# - portage's attempt to strip libpthread.so.0 breaks gdb thread
-# enumeration: bug #697910. This is quite subtle:
-# * gdb uses glibc's libthread_db-1.0.so to enumerate threads.
-# * libthread_db-1.0.so needs access to libpthread.so.0 local symbols
-# via 'ps_pglobal_lookup' symbol defined in gdb.
-# * 'ps_pglobal_lookup' uses '.symtab' section table to resolve all
-# known symbols in 'libpthread.so.0'. Specifically 'nptl_version'
-# (unexported) is used to sanity check compatibility before enabling
-# debugging.
-# Also see https://sourceware.org/gdb/wiki/FAQ#GDB_does_not_see_any_threads_besides_the_one_in_which_crash_occurred.3B_or_SIGTRAP_kills_my_program_when_I_set_a_breakpoint
-# * normal 'strip' command trims '.symtab'
-# Thus our main goal here is to prevent 'libpthread.so.0' from
-# losing it's '.symtab' entries.
-# As Gentoo's strip does not allow us to pass less aggressive stripping
-# options and does not check the machine target we strip selectively.
-
-# We need a new-enough binutils/gcc to match upstream baseline.
-# Also we need to make sure our binutils/gcc supports TLS,
-# and that gcc already contains the hardened patches.
