kumquat-buildroot/package/uclibc/0.9.33.2/uclibc-0041-libc-add-posix_fallocate.patch
Peter Korsgaard 055f1c02d3 uclibc: add upstream 0.9.33 fixes 
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
