On hppa and ia64, the macro DL_AUTO_FUNCTION_ADDRESS() uses the
variable fptr[2] in it's own scope.
The content of fptr[] is thus undefined right after the macro exits.
Newer gcc's (>= 4.7) reuse the stack space of this variable triggering
a segmentation fault in dl-init.c:69.
To fix this we rewrite the macros to make the call directly to init
and fini without needing to pass back a constructed function pointer.
Autoconf has been deprecating configure.in for quite a long time.
Rename all our configure.in and preconfigure.in files to .ac.

Resolves: #15465
The program name may be unavailable if the user application tampers
with argc and argv[]. Some parts of the dynamic linker caters for
this while others don't, so this patch consolidates the check and
fallback into a single macro and updates all users.
Joseph Myers noted that there were several old and really very
incorrect values in the hppa libm-test-ulps. This patch removes
all of the ulps values for ceil, floor, rint, round, trun,
llrint, and llround, all of which were previously incorreclty
added (including some negative values which are really wrong).

* sysdeps/hppa/fpu/libm-test-ulps: Remove old values for ceil, floor,
rint, round, trunc, llrint, and llround.
Update libm-test-ulps for hppa. There are a few entries
with 4 or 5 ulps, but these appear to be expected. A more
thorough review will be required if hppa switches long-double
to a different type.

* sysdeps/hppa/fpu/libm-test-ulps: Regenerate.
The following patch fixes both _FPU_GETCW and
_FPU_SETCW for hppa. The initial implementation was
flawed and not well tested. We failed to set cw,
and passed in the value of a register to fldd.
This patch fixes both of those errors and allows
the libm tests to pass without failure.
