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

108 allows you to specify an additional target arch.

124 help
125 If you're specifying an addition target architecture,
126 you'll probably need to also provide options to make
127 the compiler use this alternate arch.
128
129 For example, if you're building a compiler that can build
130 both powerpc and powerpc64 binaries, you'll need to
131 specify -m64 here.
