There you have the reason: OBS destroyed .o, .a or whatever files for the
non-native architecture. This was the only workaround we had.

Richie, before you revert any such workaround, please assure that it can
actually link without it. Last Hackweek I had prepared a simple "testsuite" for
linking target binaries here:
https://build.opensuse.org/project/show/home:a_faerber:branches:devel:gcc:cross-test

Of course the links broke due to gcc updates since, and it uncovered the
epiphany cross-compiler having regressed, so to get it accepted I assume we'd
at least need to suppress the package from showing as Failed...
