Subject: [PATCH 0/2] infer CROSS_COMPILE from ARCH for LLVM=1 LLVM_IAS=1

We get constant feedback that the command line invocation of make is too
long. CROSS_COMPILE is helpful when a toolchain has a prefix of the
target triple, or is an absolute path outside of $PATH, but it's mostly
redundant for a given ARCH.

Instead, let's infer it from ARCH, and move some flag handling into a
new file included from the top level Makefile.

Nick Desaulniers (2):
  Makefile: move initial clang flag handling into scripts/Makefile.clang
  Makefile: drop CROSS_COMPILE for LLVM=1 LLVM_IAS=1
