gcc: backport patch to fix miscompilation on mips64
Backport a patch to fix miscompilation on mips64.
We've observed strange behaviour of `systemctl status <xxx> on qemumips64.
The output of the command is like `systemctl show <xxx>', which is incorrect.
The problem is due to the miscompilation of gcc for mips64 platform, thus
backporting patch from upstream to fix this problem.
