-	* gcc/gcc.c (main): Add support for external spec file via the GCC_SPECS env var
-	and move the process of the user specifed specs.
-
-    This allows us to easily control pie/ssp defaults with gcc-config profiles.
-    Original patch by Rob Holland
-    Extended to support multiple entries separated by ':' by Kevin F. Quinn
-    Modified to use getenv instead of poisoned GET_ENVIRONMENT by Ryan Hill
