Hello Linaro CI Team,
This looks unrelated to the patch. It only defines LINK_SSP_SPEC inside the DEFAULT_LIBC == LIBC_MUSL block of gcc/config/linux.h plus two rs6000 headers, so nothing from it is compiled into an aarch64-linux-gnu build. To be sure I built aarch64-linux-gnu cross compilers from master with and without the patch using the same configure flags as this CI, and xgcc -dumpspecs output is byte-identical, while the same tree targeted at aarch64-linux-musl does show the new -lssp_nonshared spec.
The failing test is a gcov prime-paths count, and the build's own results.compare.txt says "No regression found in 3 common sum files". Happy to dig further if anyone sees a connection I am missing.
Thanks, Sunil Dora
