Noticed that "test -d" on an empty string returns true, and so
the makefile attempts to build libraries even if they have been
disabled in configuration.  Fixed this by adding an additional
check for a non-empty string as was done in other places in the
Makefile.  Fixed for both sky130 and gf180mcu.
