After automatically discovered "specs" file is loaded, or in its
absence "built-in" specs are generated; attempt to discover
"specs.overlay" and load it.
Unlike "specs", "specs.overlay" allows using "%include",
"%include_noerr" and "%rename" commands, similar to user provided
`-specs` on the command line.
Then continue to parse and load any user provided `-specs` on the
command line.
gcc/ChangeLog:
* gcc.cc (driver::set_up_specs): Parse and load specs.overlay
by default, with all commands allowed.
