I assume you mean it tests almost anything, in which case I thought the 
source tiny enough to not elicit any more loads that could be matched. 
But the test is annoyingly system dependent.

How about the patch below?

I used nonpic instead of "!fpic", as check_effective_target_fpic tests 
whether -fpic/-fPIC is supported in the driver, which will obviously 
return true even if we're not generating PIC code.  OTOH 
check_effective_target_nonpic tests whether we are generating PIC code 
by checking "#if __PIC__" which I believe is what we want.

Does this work for everyone?
