[MinGW] PR target/19970: Java unnecessarily disabled for MinGW in top-level configure

Hi,

  Java and its libraries have been building for the MinGW
targets since at least GCC 3.3, but they are still enumerated
in noconfigdirs for MinGW targets in the top-level configure
script. Because of this, libgcj is not build for MinGW
even if --enable-languages lists java - an explicit
- --enable-libgcj is needed to overcome this. Recently,
target-boehm-gc was also added to this list (and whereever
else ${libgcj} was listed), exacerbating the problem.

This patch removes this unnecessary enumeration from
configure.in. Regenerating configure using FSF autoconf
2.13 shows that only this line is affected in the generated
script and therefore it should be pretty safe even this
late in the release cycle (it affects *only* MinGW in any
case).

OK for mainline?

Thanks,
Ranjit.
