hppa: Use __prlimit64 as the internal name.
Fix a build failure by using __prlimit64 as the internal
function name for the versioned symbol prlimit64. Without
this patch the build system attempts to alias prlimit64
to itself and that is invalid.

rtld: limit self loading check to normal mode only
Commit glibc-2.14~10 disallowed rtld self loading to avoid a segfault
that used to happen when rtld was loading itself in normal mode.
Unfortunately, that commit disallowed all modes of self loading,
including those that used to work before. This change limits the check
for self loading to normal mode only, so that instruments like ldd could
handle rtld properly.
The convert_bit macro allows the compiler to translate the bit
positions more efficiently. The assumption of only running at
program startup allows eliding the __ieee_get_fp_control call.

tile: fix type of prfpregset_t in <sys/procfs.h>
The previous dummy definition (as type int) was fine in general, since
tile doesn't have floating-point registers, but it confused gdb's
configure, leading to later compile errors. This change also makes
prfpregset_t parallel to prgregset_t, which seems like generally the
right thing regardless of the non-existence of the actual registers :-)
Return requested size for malloc_usable_size when MALLOC_CHECK_ > 0
[BZ #1349]
malloc_usable_size returns the usable size in an allocated chunk,
which may be >= the requested size. In the case of MALLOC_CHECK_ being
exported to > 0 however, only the requested size is usable, since a
magic value is written at the end of the request size to trap writes
beyond request bounds. Hence, when MALLOC_CHECK_ is exported to > 0,
malloc_usable_size() should return the request size.

Don't make ttyname* fail if proc filesystem is not available
The ttyname and ttyname_r functions on Linux now fall back to

mips: clear condition bit 23 in fpu too
We've been carrying this in Gentoo for quite a long time to fix some test
failures that people hit.
Original message:
> make[4]: *** [/glibc/glibc-package-2.3/mips-linux/obj/math/test-fpucw.out] Error 1
This test fails since the read back fpu control word is 0x80000 instead
of 0x0. I wonder if this patch is correct:
...
which additionally masks out the condition bit 23 - note that the other
condition bits (25-31) are masked out too?
