Fix linking error for hlc.par.gc grade on Darwin.

Fix linking error for hlc.par.gc grade on Darwin.  The problem was that the
"-undefined suppress" option is not allowed with two level namespaces.
The solution is to use "-undefined dynamic_lookup" instead.
However this means the MACOSX_DEPLOYMENT_TARGET environment variable must be
set to 10.3 since this feature will not work on Mac OS < 10.3.  To allow
hlc.gc.par to be built on Mac 10.3, but targetted for Mac OS 10.0 - 10.2 add
a configuration option to force the use of flat namespaces (the
"-undefined suppress" option may be used with flat namespaces).

configure.in
	Add --enable-darwin-flat-namespace option.  This is the default
	for Mac OS < 10.3.  For Mac OS 10.3 two level namespaces are used
	unless this option is given.

	Set a variable to cause the MACOSX_DEPLOYMENT_TARGET environment
	variable to be set if two level namespaces are being used.

scripts/mmake.in
scripts/ml.in
scripts/mmc.in
	Set the MACOSX_DEPLOYMENT_TARGET environment variable wherever the
	linker may be called.
