[kvm-unit-tests,v2,0/4] Support cross compiling with clang

Message

Modify configure to allow --cc=clang and a cross-prefix to be specified
together (as well as --cflags). This allows compiling with clang, but
using cross binutils for everything else, including the linker. So far
tested on riscv 32- and 64-bit and aarch64 (with some hacks to the code
to get it to compile - which is why there's no gitlab-ci patch for aarch64
in this series). I suspect it should work for other architectures too.

v2:
 - fix building with clang and --config-efi by suppressing a warning
 - added riscv clang efi build to CI
 - picked up Thomas's tags

Andrew Jones (4):
  riscv: Drop mstrict-align
  Makefile: Prepare for clang EFI builds
  configure: Support cross compiling with clang
  riscv: gitlab-ci: Add clang build tests
