Subject: start of improved compiler handling, mostly derived from the existing
 gcc buildlink2.mk files and splitting the non-buildlink2.mk bits out into
 compiler.mk.

this allows USE_GCC2 and USE_GCC3 to work with non-buildlink2 packages
again.

+# This Makefile fragment implements handling for supported

+#
+# The following variables are used:
+#
+# USE_GCC2
+#	Use pkgsrc gcc2 from lang/gcc. This is a user-only variable
+#	which must NOT be set in package Makefiles.
+#
+# USE_GCC3
+#	use pkgsrc gcc3 from lang/gcc3. This is a user-only variable
+#	which must NOT be set in package Makefiles.
+#
+# USE_GCC_SHLIB
+#	Indicates that a package uses GCC shared libraries, so we
+#	register a runtime dependency on the compiler package.
+#
+# The following variables are reserved for future use:
+#
+# USE_MIPSPRO
+#	Use the Silicon Graphics, Inc. MIPSpro compiler.
+#
+# USE_SUNPRO
+#	Use the Sun Microsystems Inc. WorkShop/Forte/Sun ONE Studio
+#	compiler collection.
