[gentoo-user] CHOST missing in no-multilib stage3 make.conf

[gentoo-user] CHOST missing in no-multilib stage3 make.conf

[Walter Dnes]

  Beginning the install (AMD64 no-multilib).  I downloaded
stage3-amd64-nomultilib-20171215T184104Z.tar.bz2 and extracted.  Here's
make.conf...

=========================================================================
# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /usr/share/portage/config/make.conf.example for a more
# detailed example.
CFLAGS="-O2 -pipe"

# NOTE: This stage was built with the bindist Use flag enabled
PORTDIR="/usr/portage"
DISTDIR="/usr/portage/distfiles"
PKGDIR="/usr/portage/packages"

# This sets the language of build output to English.
# Please keep this setting intact when reporting bugs.
LC_MESSAGES=C
=========================================================================

  I tried a couple of different mirrors.  No CHOST line. The example
file usr/share/portage/config/make.conf.example shows...

===========================
CHOST="x86_64-pc-linux-gnu"
===========================

  I could insert that, but I wonder if anything else is screwed up.

This silently disappeared some time ago. It's set in the profiles now;
for example, the file "profiles/arch/amd64/make.defaults" sets

  CHOST="x86_64-pc-linux-gnu"

  Thanks.  That's good to know.  This could've used a brief news item to
avoid scaring people.  I'll file a documentation bug because
usr/share/portage/config/make.conf.example still shows an explicit CHOST
setting line.  While I'm at it, I'll ask them to mention "-march=native"
in CFLAGS/CXXFLAGS.

CHOST is still a valid setting in make.conf, so removing it from the
example is not necessary.

Setting CHOST is still necessary for archs like x86, on which you have
i486, i586 and i686 variants.
