Even with this patch, there are still failures on sparc-sun-solaris2.12:

FAIL: gcc.dg/plugin/must-tail-call-1.c -fplugin=./must_tail_call_plugin.so (test for excess errors)

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/plugin/must-tail-call-1.c:12:10: error: cannot tail-call: target is not able to optimize the call into a sibling call

FAIL: gcc.dg/plugin/must-tail-call-2.c -fplugin=./must_tail_call_plugin.so (test for excess errors)

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/plugin/must-tail-call-2.c:32:10: error: cannot tail-call: target is not able to optimize the call into a sibling call
