[PATCH] removes some unused targets

[Rafael Espíndola <rafael dot espindola at gmail dot com>]

All frontend except java have something analogous to
treelang TREELANG: ...

in their Make-lang.in. Only the lowercase target is used. The attached
patch removes the other.

Tested with:
../gcc/configure
--enable-languages=c,c++,fortran,java,objc,obj-c++,treelang
--prefix=/work/gcc/inst/

make bootstrap
make install

:ADDPATCH build:
