improve macOS shared library building and use by calc

Browse Source 
Dropped the use of Makefile variable ${SET_INSTALL_NAME}.
Under macOS it was always needed, elsewhere it was not.

Under macOS, the current version of both libcalc and
libcustcalc are set to the current calc release version.

Under macOS, to reduce dependency chains, we remove functions and
data that are unreachable by the entry point or exported symbols.
In particular, the linker is run with "-dead_strip".
