[gentoo-embedded] libgcc_s.so and gcc-config on embedded system

[Sergey Mironov <ierton@gmail.com>]

Hi. I recently faced (probably well-known) problem while setting up my embedded
/usr/arm-module3-linux-gnueabi  system tree. The problem is that
/lib/libgcc_s.so does not exist. Here is typical error message:

~ # bash
bash: error while loading shared libraries: libgcc_s.so.1: cannot open
shared object file: No such file or directory

I know that there is a workaround -  copying this lib from
/usr/lib/gcc/.. to /usr/lib (paths are relative to arm's root). Also,
manual [1] suggests installing gcc on target system and using host's
gcc-config. I tried it and failed. My actions were:

emerge-arm-module3-linux-gnueabi gcc
ROOT=/usr/arm-module3-linux-gnueabi gcc-config -l

I looked inside host's gcc-config. Looks like it only works with
NATIVE compiler's libgcc_s.so. It treats arm's gcc as cross-compiler
despite the fact that arm's gcc is actually native for arm system.
Well, I install gcc-config on arm. It turns out, that gcc-config
depends on libgcc_s itself.

~ # gcc-config
/bin/bash: error while loading shared libraries: libgcc_s.so.1: cannot
open shared object file: No such file or directory

Funny. Should I mail gcc-config bug?

Sergey.
