[PATCH:,hppa] Fix loading of global pointer in _start
Commit Message
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.
Change has been tested on Debian Linux.
Please install if okay.
Regards,
Dave Anglin
