librtld_db only needs libutil.h to build, not the libproc library. So
it can safely use its header and allow libproc to depend on librtld_rb
to be built first to link. This is required after fixing ld --sysroot
in r291226.

WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.
