The output of the command is like `systemctl show <xxx>', which is incorrect. This patch is from gcc bugzilla's attachment. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81803 The patch hasn't been merged into gcc. But it does solve the above problem.

We solved that by using tweaking FULL_OPTIMIZATION for mips64 to have "-fno-tree-switch-conversion -fno-tree-tail-merge". Now systemd has been upgraded to 234, and we don't have the above problem any more, thus removing these flags.
