delete "was".

Why is $(INSTALL_MERC_LIB_DIR) a bogus default value?  Is that because 
it gets set by mmake and so is blank when mmc is called outside of 
mmake?  Does this mean that when you build shared libraries with mmc 
--make you must either set INSTALL_PREFIX in the environment or pass 
--shlib-linker-install-name-path?  Or is that value of INSTALL_PREFIX 
coming from the runtime (i.e runtime/mercury_conf*.h)?

Also if I build a library, but don't install it, can I still link with 
the library?

Also I assume everything still works with mmake :-)
