While building a cross compiler for sparc-leon with Go enabled, I get the
following ICE:

Please submit a full bug report, with preprocessed source.
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.
I can provide more info if needed, or rebuild with a debug build.
The ICE has been first observed on 12.2.0 tgz and reproduced on today's master
(bbcb84bb)
