Add two uClibc 0.9.33.2 patches which fix issues relating to high signal
number handling on MIPS.
The first patch (0056) fixes _NSIG (and as a result __SIGRTMAX) to match
glibc. This fixes GDB on MIPS with uClibc, which cannot handle
__SIGRTMAX == 128 and emits the error:
GDB bug: target.c (gdb_signal_from_host): unrecognized real-time signal
This patch is from uClibc commit 2da958760f79 (MIPS: set _NSIG to
128, not 129. This matches glibc.) and applies without conflicts.
The second patch (0057) fixes the wait status macros to correctly
interpret status 0x007f on MIPS (other arches don't have signal 127).
This patch is from uClibc commit 4a96b9486871 (bits/waitstatus.h:
correctly interpret status 0x007f on MIPS) and applies without
conflicts.

Add uClibc 0.9.33.2 patch to fix arch specific eventfd definitions,
particularly EFD_NONBLOCK. The definition in sys/eventfd.h was 04000
(0x800), however MIPS uses 0200 (0x80). This resulted in QEMU built for
MIPS hanging at various points until input is received due to a blocking
poll of stdin.
The patch is a backport of uClibc commit fd355bc1dbcb (eventfd.h: Use
new "bits/" scheme for arch-specific flags). The only conflict was minor
in Makefile.in.

The pread/pwrite handling on the 0.9.33 branch doesn't take into
consideration architectures with an ABI requiring natural alignment for
64bit arguments (afaik ARM EABI, MIPS O32, PPC, SH and Xtensa), causing
havoc.
The issue has been brought with the uClibc developers, but so far a fix is
not available - So lets revert the patches for now as they cause real
issues.

Upstream has a large number of patches lined up for the next 0.9.33.x bugfix
release;
http://git.uclibc.org/uClibc/log/?h=0.9.33
Add them here, as atleast some of them are quite critical (E.G. the eventfd
issue gets triggered by recent glib versions).
I've skipped the microblaze and xtensa fixes as we don't currently support
those with 0.9.33.2.
Drop uclibc-0002-Add-definition-of-MSG_WAITFORONE-and-MSG_CMSG_CMSG_CLOEXE.patch
as that is a subset of uclibc-0035-socket.h-pull-socket_type.h-from-eglibc.patch

uClibc picks the wrong interpreter for MIPS64/n64.
This patch fixes this problem by checking the selected
MIPS ABI instead of the MIPS variant.
The patch has been committed upstream:

This commit adds three patches to uClibc that are needed to make
Thumb2 support work properly:
uclibc-0006-arm-clone-restore-stack-pointer-just-after-return-fr.patch
uclibc-0007-arm-clone.S-Add-missing-IT-instruction-for-Thumb2.patch
uclibc-0008-arm-move-check-for-BX-to-its-own-header.patch
The first one is a necessary dependency of the second one. Both of
those patches have already been merged upstream, after 0.9.33.2. The
third one hasn't been merged upstream yet, but it has already been
submitted a while ago by Yann E. Morin, without receiving attention
from upstream.
