libjava fails to cross-build because the Makefile includes an -I/usr/include.
Removing that makes it work. I've seen this a number of times now, i386 to
alpha-linux, i386 to m68-linux, etc. The problem is this in the Makefile:
X_CFLAGS = -I/usr/include
and X_CFLAGS is part of AM_CXXFLAGS which is where it causes the problem.
I configured gcc with:
/home/tbm/scratch/gcc/configure --disable-bootstrap \
--enable-languages=c,c++,java --target=alpha-linux-gnu
--
Summary: libjava cannot be cross-built; X_CFLAGS includes
/usr/include
