hppa: fix loading of global pointer in _start [BZ #20277]
The patched change fixes a regression for executables compiled with the -p option and linked with gcrt1.o. The executables crash on startup. This regression was introduced in 2.22 and was noticed in the gcc testsuite. (cherry picked from commit 9765ffa71030efd8bb4f2ea4ed6e020fcb4bb714)
