Subject: [COMMITTED] hppa: Fix gmon static test failures
Authentication-results: sourceware.org; auth=none

The attached change fixes the following two test failures on hppa:
FAIL: gmon/tst-gmon-static
FAIL: gmon/tst-gmon-static-gprof

These tests do links using the -static option.  They also link using the PIC startup file Scrt1.o.  On hppa
in static links, the linker converts linkage table references using the PIC register, %r19, to references using
the global pointer, %dp.  However, %dp hasn't been initialized and the tests fault.

The attached patch fixes this problem.  We need to setup %dp earlier.  In the PIC case, we also need to use
a PIC pc-relative sequence that doesn't use dynamic relocations.

Committed to trunk.

Dave
