Giulio Benetti 983a191ff6 package/libnss: fix PowerPC build failure
NSS assumes <sys/auvx.h> is always present but that's not true, so add a
patch to check if it exists or not.

Subject: [PATCH] Bug 1614183 - Check if PPC __has_include(<sys/auxv.h>)
Some build environment doesn't provide <sys/auxv.h> and this causes
build failure, so let's check if that header exists by using
__has_include() helper.
