glibc: Fix scope resolution in glibc to be breadth first.
The ELF specification indicates symbol resolution should be breadth first, not
depth first.
The dl-deps.c: dl_build_locale_scope function is processing in a depth first
mode. This is causes certain symbols to be incorrectly reported when
LD_TRACE_PRELINKING=1 is enabled.
See glibc BZ #20488 for more information.
