1) fastjar problem: don't build java.  Java is not supported on any PA
   port at this time.  This is because we don't have a libffi port.
   Use `--enable-languages=' to explicitly specify the set of languages
   to build.

   As of 3.4, support for building GCC with a non ANSI compiler has been
   dropped.  Thus, it will no longer be possible to build GCC 3.4 and
   later with the bundled HP C compiler.  However, fastjar requires an
   ANSI compiler to build even in earlier versions of GCC.

2) CFLAGS: don't try to use CFLAGS to specify compiler options (e.g.,
   CFLAGS="+DAportable -Ae +O2").  A better way is to use CC (e.g.,
   CC="cc +DAportable -Ae").  This is the preferred technique as the
   config.guess script uses CC for its guess.  You can also use
   STAGE1_FLAGS to set the CFLAGS for stage1 of the bootstrap.
