Hi!
Not all OSes have regex.h and not all OSes that do have REG_STARTEND macro
support.
Conditionalize the test on that.
Tested on x86_64-linux without/with Martin's libsanitizer fix, committed to
trunk as obvious.

* c-c++-common/asan/pr98920.c: Only include regex.h if the header
exists. If REG_STARTEND macro isn't defined, just return 0 from main
instead of the actual test.
