Update the architecture API: architecture help is mandatory.
Update all architectures (some with pointer to the specs, when available).

1 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.0/gentoo/00_all_gcc-trampolinewarn.patch
2 This trivial patch causes gcc to emit a warning whenever
3 it generates a trampoline. These are otherwise hard to
4 locate. It is rigged to default ON - to have it default
5 to OFF remove the text 'Init(1)' from the common.opt
6 patch, leaving just 'Common Var(warn_trampolines)'.
