uclibc-git: Update for building systemd

This adds uclibc patches to build systemd there are
new functions that are used by systemd which are needed

Additionally when using gold linker to build userspace
based on uclibc there are spurious hidden symbol that
show up in librt.so and libc.so which should not exist

So we patch uclibc for that
