glibc: Fix scope resolution in glibc to be breadth first.

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.
