Patch for gdb build on hppa hp-ux

[Steve Ellcey <sje@cup.hp.com>]

This patch fixes a build problem on hppa hp-ux.  This is the first of
two patches I have that allow me to build gdb on hppa hp-ux.  The build
has been broken (for me at least) for some time.  This is the only HP
specific change that was needed.  Tested by building gdb on hppa hp-ux.

OK to checkin?
