Progress sometimes demands that old features be removed.  I think this
is a feature that should be removed.  I accept that you still need this
functionality, but I think it should be implemented differently.

standard_startfile_prefix is initialized to a string in gcc.c, and never
modified.  This is just begging to have a const type qualifier.  Asking
to remove the const because of an unusual macro use does not make
sense.  It is better to fix the unusual macro use.

standard_startfile_prefix_0 would not be initialized to a string, and
would have a comment indicating that it exists for communication with
the GCC_DRIVER_HOST_INITIALIZATION/UPDATE_PATH_HOST_CANONICALIZE macros
that some ports define.  This would make the relationship explicit, and
easier to maintain.
