Added COMMON_ADD Makefile facility

Browse Source 
Added the makefile variable ${COMMON_ADD} that will add flags
to all compile and link commands. The ${COMMON_ADD} flags are
appended to both ${COMMON_CFLAGS} and ${COMMON_LDFLAGS}.  This
facility is available to nearly all platforms except those with
very old make comamnds that do not understand the += operator.

Example on masOS (Darwin), one may invoke clang's -fsanitize
facility by:

    make clobber all COMMON_ADD='-fsanitize=undefined -fsanitize=address'

Another example.  To force C warnings to be treated as errors:

    make COMMON_ADD='-Werror'
