Patch taken from Debian[1], largely broken on HPPA without and several
tests give segmentation faults[2].
Needs upstreaming if someone familiar with HPPA wants to give this
attention. Note forkfd is essentially maintained in qtbase's repo[3]
rather than truly third party.

Description: Change how stack grows on HPPA.
On HPPA stack grows upwards. This patch introduces this change for
this 3rd party code.
