When building GCC with --enable-default-ssp, the stack protector is
enabled for got-load.C, causing additional GOT loads for
__stack_chk_guard. So mem/u will be matched more than 2 times and the
test will fail.
Disable stack protector to fix this issue.
gcc/testsuite:
* g++.target/loongarch/got-load.C (dg-options): Add
-fno-stack-protector.
---
Ok for trunk?
