The attached patch fixes an oversight in hppa_profile_hook. We need tomark the SYMBOL_REFfor _mcount as a function label. When the -mlong-call option is used,the call to _mcount is convertedto an indirect call. In that case, we need the function pointer topoint to a procedure labelwhich points to a function descriptor. This is necessary to correctlyload the PIC register. Marking

the SYMBOL_REF causes this to happen.

Tested on hppa-unknown-linux-gnu with no regressions.  Committed to trunk.

This bug caused a build error for gcl. Thanks to Camm Maguire fordebugging the problem.
