[PATCH 1/2] Makefile.lib: introduce lwl-y for lowlevel code

[Jean-Christophe PLAGNIOL-VILLARD]

The lowlevel code is expected to be present only ONCE

in PBL is enabled otherwise in barebox

This fix the module support with PBL and allow to reduce the size of barebox
by drop the lowlevell init in barebox as the compiler does not discard it
