[committed] Fix gcc.dg/pr48616.c on hppa*-*-hpux*

[John David Anglin]

Test fails on hppa*-*-hpux* because specified alignment exceeds maximum
common alignment.  So add -fno-common option with target hppa*-*-hpux*.

Tested on hppa2.0w-hp-hpux11.11 and hppa64-hp-hpux11.11.  Committed to
trunk and 4.6 branch.
