[Bug java/30591] Cross build fails because native gcj needed to build ecjx

Marking as FIXED as it now works for me *if* I use a current native GCC to
build the cross compiler.

I am prepering a documentation patch that explains my interpretation of the
requirements.

You write it needs a host version of gcj,
your host is i686-pc-linux-gnu and
configure looks for i686-pc-linux-gnu-gcj?

Seems correct to me? What gcj should be searched for? The only problem I'm
currently aware of is that the compilation of ecj.jar uses
-findirect-dispatch. This fails for static compilations since
indirect-dispatch doesn't work anymore with such compilations since some bc abi
(or whatever) changes. It can easily be fixed by modifying libgcj.a.spec.

Is this still a problem?
I thought it was ironed out a while ago.

I have not tested it recently.  I will try to test again.

This is actually contains the error from the build output this time:


i686-pc-linux-gnu-gcj -o ecjx -findirect-dispatch

FWIW I don't think we want to fail outright if no suitable gcj is found.
The whole business with compiling and installing ecj.jar is a convenience,
not a strict necessity.  The user can always make his own ecj1 somehow
(e.g, I use a shell script).

So one idea would be to look for a gcj for the build machine, and if not
found, disable compilation of ecjx.

What do you think?
