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

["daney at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

ecjx is a java program used as part of the gcj compilation process.  Because it
is written in java and runs on the host, it needs a host version of gcj to
build it.

Here is the error I am getting:

make[3]: *** [ecjx] Error 127
make[3]: Leaving directory
`/home/daney/gccsvn/mipsel-trunk/mipsel-linux/libjava'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory
`/home/daney/gccsvn/mipsel-trunk/mipsel-linux/libjava'
make[1]: *** [all-target-libjava] Error 2
make[1]: Leaving directory `/home/daney/gccsvn/mipsel-trunk'
make: *** [all] Error 2

There seem to be two ways to fix this:

1) In a cross build, build a complete gcc/g++/gcj in build-i686-pc-linux-gnu
along with fixincldes and libiberty.

2) Have configure check for a good version of gcj that is already installed and
use that
