Add <arch-triple>-clang links

Setting CC / CXX variables to plain clang / clang++ fails due
to qemu acceleration: clang defaults to the same target as the host,
and clang-accel's host is x86_64. CC containing multiple
words (e.g. "clang -target <target-triple>") sometimes leads to
separate problems arising from shell word-splitting.

Therefore this change (along with a companion change to qemu-accel)
creates <arch triple>-clang{,++} links in /usr/bin
