Summary:                    Build fails for ARM920T, c++ compiler/gcj build
Description: 
When attempting to build toolchain for ARM920t, with "Build/install c++
compiler and libsdc++" option and "build/install java compiler and
libgcj", the following error shows up no matter what distro I use (Fedora,
Debian, Gentoo, etc.):

I must have Java support on my toolchain, and this failure to compile
makes things very frustrating.  I saw something similar on these boards,
with the response being ~"fix your headers.", and stating that Gentoo had
correct headers. I'm using Gentoo, and it's apparently not helping. Please
help. Thanks,

the "ft" after "#Ok... that's enough of that" is my OCR software
incorrectly identifying the # symbol. I'm running this in a VM, and didn't
feel like piping the output over, so there may be a recognition error or
two. I took care to correct the rest of the output.

I have seen the same thing for the AVR32 build.
I traced it back to "configure" not beeing able to link.
This was because "crt1.o" was not found, when linking.
That disabled creating the *.so files.

I find this strange, since there is no crt1.asm in gcc
except for the SH architecture.
Did not have time to investigate further.

So what can I do to get this to compile? I need gcj support or a JVM to run
on my busybox build. And I don't have room to statically link GCJ with
glibc (47MB for a  hello world app). Is there any toolchain that I can use
to build gcj cross-compiling support with static linking against uClibc?
