sys-libs/glibc: fix glibc-headers bootstrap on non-multilib host
The error is found by wm_ attempting to build a cross-compiler
CHOST=powerpc-unknown-linux-gnu CTARGET=mips64-unknown-linux-gnu
Boostrap failed on glibc-headers (./configure phase) as:
configure:2623: powerpc-unknown-linux-gnu-gcc -mabi=n32 -c \
-O1 -pipe -U_FORTIFY_SOURCE conftest.c >&5
powerpc-unknown-linux-gnu-gcc: error: \
unrecognized command line option '-mabi=n32'; did you mean '-mabi=d32'?
Note how target's ABI is mexed into host's compiler flags.
The error above happens on every host=non-multilib target=multilib combination.
I've reproduced it on:
CHOST=i686-pc-linux-gnu CTARGET=mips64-unknown-linux-gnu
The fix is not to inject target's CFLAGS ABI into CC for
USE=headers-only bootstrap step as we don't have cross-compiler yet.
Tested by successfully bootstrapping cross-compiler on
CHOST=i686-pc-linux-gnu CTARGET=mips64-unknown-linux-gnu
Package-Manager: Portage-2.3.26, Repoman-2.3.7
