What does java-config have to do with it when the message clearly tells
you what to do:

==> Re-emerge sys-devel/gcc with "java" and "gcj" enabled <==

As seen here:

 emerge -pv gcc

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild   R   ] sys-devel/gcc-3.4.4-r1  (-altivec) -bootstrap
-boundschecking -build +fortran -gcj +gtk -hardened -ip28 (-multilib)
-multislot (-n32) (-n64) +nls -nocxx -nopie -nossp -objc -static
-vanilla 0 kB

See that "-gcj"? That's your problem; the ability to compile java has
not been compiled into your compiler. If there's a 'java' USE flag for
your version of GCC, set that as well.

Re-emerge gcc with the appropriate USE flags, then try your original
emerge again.
