[PATCH v2 13/14] configure: don't try a "native" cross for linux-user
As 32 bit x86 become rarer we are starting to run into problems with
search paths. Although we switched to a Debian container we still
favour the native CC on a Bookworm host. As a result we have a broken
cross compile setup which then fails to build with:
BUILD i386-linux-user guest-tests
In file included from /usr/include/linux/stat.h:5,
from /usr/include/bits/statx.h:31,
from /usr/include/sys/stat.h:465,
from
/home/alex/lsrc/qemu.git/tests/tcg/multiarch/linux/linux-test.c:28:
/usr/include/linux/types.h:5:10: fatal error: asm/types.h: No such file or directory
5 | #include <asm/types.h>
| ^~~~~~~~~~~~~
compilation terminated.
make[1]: *** [Makefile:119: linux-test] Error 1
make: *** [/home/alex/lsrc/qemu.git/tests/Makefile.include:50:
build-tcg-tests-i386-linux-user] Error 2
This is likely to affect more and more linux-user builds so wrap the
whole check in a test for softmmu targets (aka bare metal) which don't
worry about such header niceties. This allows us to keep using the
host compiler for softmmu tests and the roms.

v2
- split fix for tests/docker: replace fedora-i386 with debian-i686
as still in my tree ;-)
- didn't apply dpb rb due to change requested by bonzini
