[ANNOUNCE] Libgcj in gcc tree availability.

[Robert Lipe]

When performing a 3-stage with a non-gcc bootstrap compiler,
GCC-specific flags are used for building fastjar.  This sends the build
up in smoke.  I'll leave it to you to decide whether the wrong compiler
is used or the wrong flags are used.  It's also discomforting that the
flags that compiler sees aren't what's displayed.

Sure enough, the Makefile echos one thing and then runs another
(GCC-specific) thing.  I suspe that somehow it needs to use the freshly
built compiler and not the bootstrap compiler.
