configure.ac: respect 'g' variants of libtool/libtoolize
BSD OS'es (OS X for me) provide GNU tools with prefixed 'g'. To find correct
versions of libtool/libtoolize on those systems search also for
glibtool/glibtoolize.

1 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/53_all_gcc4-superh-default-multilib.patch
2 The gcc-3.x toolchains would contain all the targets by default. With gcc-4,
3 you have to actually list out the multilibs you want or you will end up with
4 just one when using targets like 'sh4-linux-gnu'.
6 The resulting toolchain can't even build a kernel as the kernel needs to build
7 with the nofpu flag to be sure that no fpu ops are generated.
9 Here we restore the gcc-3.x behavior; the additional overhead of building all
10 of these multilibs by default is negligible.
