kaffe configure bug

[Patrick Tullmann]

Kaffe's configure script resets 'cross_compiling' in the GCJ option
test code.

Some background (as I understand things): Kaffe's configure script is
supposed to honor the KAFFEH environment variable if Kaffe is being
cross-compiled (it uses KAFFEH instead of the cross-compiled kaffeh to
build .h files).  The configure script checks the 'cross_compiling'
variable to determine this.  The OSKit config.frag explicitly sets
'cross_compiling'.

The problem is that the GCJ configure test magic is unsetting
'cross_compiling' for some reason (the AC_PROG_CXX?).  If I configure
for the OSKit with '--disable-gcj' then the compile proceeds just fine
(it uses $KAFFEH), if I do not explicitly disable GCJ support, the
magic in that part of configure.in ends up unsetting cross_compiling,
and I can't build Kaffe.

I'm not sure what the real problem is, or how to fix it.  I don't have
a problem disabling GCJ support, just a heads up.  I do not know if
other cross-compiler envs have this problem.

This is from an early February Kaffe CVS snapshot.  I haven't upgraded
(and won't) because I understand that recent libtool changes break
Kaffe on FreeBSD.

I tried to submit a bug report but the submission bounced.
