My patch for GCC 5 directory names

[Richard Biener]

I promised to send out my pat^Whack.  Before building I introduce
gcc/FULL-VER as copy of gcc/BASE-VER and adjust gcc/BASE-VER to
just the major number.  Then I only need the following small
patch (where I don't speak enough tcl for fixing libjava.exp "properly").

Without the FULL-VER trick the patch would be much larger (BASE-VER
is referenced a lot).  For a "real" patch (including configury) we
probably want to generate a BASE-VER in the toplevel (or have
a @BASE-VER@ substitute).

Richard.
