IA64 HP-UX patch for fp-int-convert-float128-timode.c

[Steve Ellcey]

The test fp-int-convert-float128-timode.c fails on IA64 HP-UX and Linux.
For Linux the break is reasonable because some routines were added for
backwards compatibility when IA64 Linux went from using TFmode for 80
bit long double to using XFmode.

But for IA64 HP-UX, which have always used TFmode for 128 bit long
doubles, these routines should not be used.  This patch is to filter out
these routines from libgcc.  Since the fp-int-convert-float128-timode.c
test now passes on HP-UX I also changed it to only be XFAIL'ed on Linux.

Since the patch is HP-UX specific I will check it in tomorrow unless
there are objections.
