Revert to rev 1.91. Revs 1.9{2,3} were causing problems for people with

pre-Aug 4.0-CURRENT worlds and those with pre-GCC 2.95.2 worlds.

The problem with pre-Aug worlds is the installed Byacc and Bison doesn't
have necessary changes to compile either GCC 2.95 or EGCS 1.1.x.

The problem with pre-GCC 2.95 worlds is libgcc is built with the wrong
compiler.  See rev 1.17 of src/gnu/lib/libgcc/Makefile (which used to live
in src/gnu/usr.bin/cc/libgcc) + commit messge for details of the requirements.
