Somehow, the build system applies -flto=thin to the host compiler,
and GCC doesn’t support this flag.
This is but the first error. When I comment out the LTO line
in d/rules the build continues for hours but then:

Interesting, this isn't the same error as in the CI.

Which should be easy to fix (I guess it is a missing path in|clang/lib/Driver/ToolChains/Gnu.c ) I don't have the bandwidth in the
next month to manage non official arch but I will be happy to take a
patch or to guide. About the lto issue, it is fixed in the branch 9 (I
am focussing my time on this branch):
