Is this similar to what I just got for sparc-rtems when compiling
libgcc2 with -mcpu=v8?

/tmp/cczMc4jN.s: Assembler messages:
/tmp/cczMc4jN.s:16: Error: Hardware capability "mul32" not enabled for
"smul".
/tmp/cczMc4jN.s:18: Error: Hardware capability "mul32" not enabled for
"smul".
/tmp/cczMc4jN.s:22: Error: Hardware capability "mul32" not enabled for
"umul".

I can prepare a PR if you think it is different.

I don't think so.  The bug I'm hitting seems to be simply that
config/sparc/t-linux64 wasn't migrated up into the libgcc configure
area properly the way that config/sparc/t-linux was.

I'm working on a fix right now.

I filed a PR for this so it doesn't get lost.

I am happy to retest whenever something changes.

Thanks.
