binutils-2.17 does not have ld or gas available for the aarch64, powerpc64, or

riscv64 family of platforms, so we don't try to build there.

However we mis-nested the arch check, causing some unintended side effects,
most notably installing binutils-2.17's ar(1) which overwrote the
intended llvm-ar(1).

Fix the if nesting so it only applies where intended.

tested on aarch64 by me, powerpc64 by gkoehler@, and riscv64 by jca@

OK miod@ robert@ gkoehler@ jca@
