[PATCH 0/3] check-uapi: improve portability for testing headers

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

While working on a series to clean up some uapi headers, I needed
to check the that the actual ABI remains unchanged. I found that
scripts/check-uapi.sh works well enough for architectures that have a
full toolchain installed, but not with the nolibc compilers I provide
on kernel.org.

I ended up with a series addressing three separate issues here, but in
the end I can now validate ABI changes across all supported architectures
and ABIs.

The third patch depends on a series from Thomas Weißschuh that was
just merged into the kbuild-for-next tree, the other ones could
also apply to older kernels. I have marked the second patch for
backports to stable kernels, this one is what caused me the most
work in debugging.

  check-uapi: link into shared objects
  check-uapi: honor ${CROSS_COMPILE} setting
  check-uapi: use dummy libc includes
