In particular for example building offload compilers where we now see:

[  856s] checking whether the target has CRLF as line terminator... no
[  856s] configure: error: in 
`/home/abuild/rpmbuild/BUILD/cross-amdgcn-gcc16-16
.0.1+git7751-build/gcc-16.0.1+git7751/obj-x86_64-suse-linux/amdgcn-amdhsa/libgfo
rtran':
[  856s] configure: error: cannot run test program while cross compiling
[  856s] See `config.log' for more details
[  856s] make[1]: *** [Makefile:14692: configure-target-libgfortran] Error

Please fix.
