This is the next part of the firmware cross compilation story, and
shows a little more the direction I would like for QEMU's configure
script.

It basically does half of half of the work: it only looks at firmware
that's distributed with QEMU (optionrom, s390-ccw, vof) and does not do
docker cross compilers yet.  However, the important part is taking
infrastructure from the recently-cleaned-up tests/tcg/configure.sh, and
moving it in the main configure script so that others can use it.

tests/tcg is actually very close to being buildable as a standalone
project, so I actually expect the compiler tests to move back to
tests/tcg, as a "configure" script of sorts which would run at Make time
after the docker images are built.  The "Cygnus" (GCC/binutils/gdb) tree
has a similar idea of "configure" doing only bare-bones tree-wide
configuration, with the rest left for Make time; so that's where I took
inspiration from.

Paolo Bonzini (12):
  tests/tcg: merge configure.sh back into main configure script
  configure: add missing cross compiler fallbacks
  configure: handle host compiler in probe_target_compiler
  configure: introduce --cross-prefix-*=
  configure: include more binutils in tests/tcg makefile
  configure, meson: move symlinking of ROMs to meson
  configure: move symlink configuration earlier
  configure: enable cross-compilation of s390-ccw
  pc-bios/optionrom: detect -fno-pie
  pc-bios/optionrom: compile with -Wno-array-bounds
  configure: enable cross-compilation of optionrom
  configure: enable cross compilation of vof
