Specify the libc type used by the external toolchain. The given value us passed as -m
flag to all gcc and g++ invocations. This is mainly intended for multilib toolchains
which support glibc and uclibc at the same time. If no value is specified, no -m flag
is passed.

Some builds may require a 'biarch' toolchain. This option
allows you to specify an additional target arch.
Most people will answer N here.
config EXTRA_TARGET_ARCH_NAME

default "powerpc64" if powerpc64
prompt "Extra architecture name" if EXTRA_TARGET_ARCH

Specify the cpu name (eg powerpc64 or x86_64) of the
additional target architecture.
config EXTRA_TARGET_ARCH_OPTS
string
default "-m64" if powerpc64
prompt "Extra architecture compiler options" if EXTRA_TARGET_ARCH
help
If you're specifying an addition target architecture,
you'll probably need to also provide options to make
the compiler use this alternate arch.
For example, if you're building a compiler that can build
both powerpc and powerpc64 binaries, you'll need to
specify -m64 here.
