See https://lists.openembedded.org/g/openembedded-core/message/200915
which allows to me to build nativesdk-gcc again.
I've built nativesdk-libgfortran and libgfortran with the patch, but
haven't used fortran in runtime at all, that's why it's an RFC, there
were also 2 warnings:
WARNING: nativesdk-libgfortran-14.1.0-r0 do_package_qa: QA Issue: File
/opt/.../usr/lib/.debug/libgfortran.so.5.0.0 in package
nativesdk-libgfortran-dbg contains reference to TMPDIR [buildpaths]
WARNING: libgfortran-14.1.0-r0 do_package_qa: QA Issue: File
/usr/lib/.debug/libgfortran.so.5.0.0 in package libgfortran-dbg
contains reference to TMPDIR [buildpaths]
which I guess were already there.
