Commenting these 3 lines frees 500M on disk and the linked binary (using such built toolchain) has the same md5 hash.
They were added in rev 40 of gcc5: osc rdiff -c 40 devel:gcc gcc5

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:cr... 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...
+* Suppress -icecream-backend subpackage +* Allow building on any architecture
