[COMMITTED] hppa: Remove warnings and fix conformance errors.


Two updates for hppa for 2.21 to build. Posted results.
I promise this is not what is holding up the release.

(1) Fix warnings.

This is a bulk update to fix all the warnings that were causing
build failures with -Werror on hppa.

The most egregious problems are in dl-fptr.c which needs to be
entirely rewritten, thus I've used -Wno-error for that.

(2) Fix conformance errors.

The sysdep.c file had __syscall_error and syscall in one file
which caused conformance issues by including syscall when
__syscall_error was linked to. The fix is obviously to split
the file and use syscall.c to implement syscall.

2015-02-05  Carlos O'Donell  <carlos@systemhalted.org>

	* sysdeps/hppa/Makefile (CFLAGS-dl-fptr.c): Add -Wno-error.
	* sysdeps/hppa/bits/setjmp.h: Union is named __jmp_buf_internal_tag.
	* sysdeps/hppa/dl-irel.h: Remove #warning.
	* sysdeps/hppa/entry.h: Provide prototype for
	__canonicalize_funcptr_for_compare and cast argument.
	* sysdeps/hppa/fpu/fegetexcept.c (fegetexcept): Add semicolon.
	* sysdeps/hppa/fpu/ftestexcept.c (fetestexcept): Likewise. 
	* sysdeps/hppa/sotruss-lib.c: New file.
	* sysdeps/unix/sysv/linux/hppa/bits/atomic.h
	(atomic_compare_and_exchange_val_acq): Use __typeof__.
	(atomic_compare_and_exchange_bool_acq): Likewise.
	* sysdeps/unix/sysv/linux/hppa/mmap.c: Use weak alias.
	* sysdeps/unix/sysv/linux/hppa/pthread.h: Include pthread.h. 

	* sysdeps/unix/sysv/linux/hppa/syscall.S: Delete file.
	* sysdeps/unix/sysv/linux/hppa/sysdep.c: Move syscall from here...
	* sysdeps/unix/sysv/linux/hppa/syscall.c: ... to here.
