For some reason, we have been inserting the ABI specification into the
middle of the target triple, when building LLVM, like so:
armv6-gnueabi-freebsd12.0
This is the wrong way around. LLVM even auto-canonicalizes it to:
armv6--freebsd12.0-gnueabi
Let's do this the right way in llvm.build.mk instead. While here,
define a proper VENDOR macro which can be overridden easily.
