gdb: workaround sparc memcpy fortify error

Building on an x86_64-linux system with --enable-targets=all fails on the
sparc code with a fortify error:

cc1: warnings being treated as errors

/usr/include/bits/string3.h:52: error: call to __builtin___memcpy_chk will

make: *** [sparc-tdep.o] Error 1

This is due to the gcc optimizer bug PR37060, so tweak the gdb_assert ()
to avoid the issue.
