libc/glibc: do not consume parameters when parsing them

Currently, there are two constructs used to parse arguments in
glibc backends, one that consumes args as they are parsed, and
one that does not.

Always use the construct that does not eat args as they are parsed.

     4 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/53_all_gcc4-superh-default-multilib.patch

     5 The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,

     6 you have to actually list out the multilibs you want or you will end up with

     7 just one when using targets like 'sh4-linux-gnu'.

     8 

     9 The resulting toolchain can't even build a kernel as the kernel needs to build

    10 with the nofpu flag to be sure that no fpu ops are generated.

    11 

    12 Here we restore the gcc-3.x behavior; the additional overhead of building all

    13 of these multilibs by default is negligible.
