[Buildroot] [PATCH 1/2] libnss: drop obsolete patch

[Baruch Siach]

uClibc implements RTLD_NOLOAD for quite some time now. Remove the patch
adding a dummy definition of RTLD_NOLOAD.

[Buildroot] [PATCH 2/2] libnss: fix build with uClibc

[Baruch Siach]

Add a patch defining AT_HWCAP2 locally since uClibc is missing this
macro. Once uClibc updates its elf.h copy we can remove this patch.

Forgot to mention autobuilder failures being fixed:

Both applied. I fixed the commit message of the second patch to include
the autoubuilder references. Thanks!
