Expand -fzero-call-used-regs test to cover gcc 11.
It turns out that gcc also has some problems with -fzero-call-used-regs,
at least v11 on mips. Previously the test in OSSH_CHECK_CFLAG_COMPILE
was sufficient to catch it with "=all", but not sufficient for "=used".
Expand the testcase and include it in the other tests for good measure.
See bz#3629. ok djm@.
