+ * 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
+ Modified to process the GCC_SPECS env var befor DRIVER_SELF_SPECS by Magnus Granberg
