uspace/Makefile.common: only generate the intended library

Because libbithenge used libblock.a, Makefile.common was trying to generate
libblock.a from the libbithenge object files. On the other hand, libbithenge
actually doesn't need libblock.a until it's linked into an executable.

36# EXTRA_CFLAGS additional flags to pass to C compiler
