glibc: Drop prelink patch

Browse Source 
With the removal of prelink, we no longer need the glibc patch for it
either.

Subject: [PATCH] elf/dl-deps.c: Make _dl_build_local_scope breadth first
According to the ELF specification:
When resolving symbolic references, the dynamic linker examines the symbol
tables with a breadth-first search.
This function was using a depth first search. By doing so the conflict
resolution reported to the prelinker (when LD_TRACE_PRELINKING=1 is set)
was incorrect. This caused problems when their were various circular
dependencies between libraries. The problem usually manifested itself by
the wrong IFUNC being executed.
[BZ# 20488]
Upstream-Status: Submitted [libc-alpha]
