[PATCH v2] glibc: don't ignore global LDFLAGS settings

[Rasmus Villemoes <rasmus.villemoes@prevas.dk>]

Two things: The -Wl,-rpath-link comment is stale (due to per-recipe
staging), so we no longer need to set our own LDFLAGS to avoid
-Wl,-rpath-link being in there. Second, overriding LDFLAGS should be
done at the recipe level so "bitbake -e" can show what is going on.
Otherwise debugging why one's global LDFLAGS tweaks are being ignored
is needlessly painful.

So pull out the LDFLAGS setting from do_compile, and change it to an
append instead of assignment.

For the benefit of future git blame: the -fuse-ld=bfd setting was
added by ac64c3b96b (glibc: always use bfd linker).

v2: Rebase to real upstream master. Note to self: "git pull" before rebasing to master.
