Provide wrappers named <triplet>-gcc and <triplet>-g++ as well, to ease cross compilation with e.g. autotools, to allow just specifying --host=<triplet>. Provide wrappers for objdump and ld that provide specific output that autotools look for. Provide <triplet>-strip as a symlink to /bin/true, since there is no strip tool available yet (and llvm-objcopy doesn't support COFF yet).
