[PATCH 2/2] Makefile: Only specify '--prefix=' when building with clang + GNU as

[Nathan Chancellor <nathan@kernel.org>]

When building with LLVM_IAS=1, there is no point to specifying
'--prefix=' because that flag is only used to find the cross assembler,
which is clang itself when building with LLVM_IAS=1. All of the other
tools are invoked directly from PATH or a full path specified via the
command line, which does not depend on the value of '--prefix='.

Sharing commands to reproduce issues becomes a little bit easier without
a '--prefix=' value because that '--prefix=' value is specific to a
user's machine due to it being an absolute path.
