Toolchain compilation problems

[David Summers]

I'm trying to compile a tool chain to run on an x86-64 machine, but 
produce code for an arm, so options to most things:

--target=armv7-hardfloat-linux-gnueabi --host=x86_64-pc-linux-gnu 
--build=x86_64-pc-linux-gnu

Software that I'm compiling is:

gcc-4.7.0
binutils-2.22
uClibc-0.9.33.2

First pass of all compiles fine, as long as threads and shared are 
disabled in gcc.

Second pass though fails, and can see the problem with this:

# echo 'main(){}' > dummy.c

So the problem seems to be that the linker isn't working, this was 
compiled via:

../binutils-2.22/configure --target=armv7-hardfloat-linux-gnueabi 
--host=x86_64-linux-gnu --build=x86_64-linux-gnu --prefix=/home/arm 
--with-lib-path=/home/arm/lib:/home/arm/usr/lib --enable-shared 
--disable-nls --with-libliberty

Now I've tried compiling both binutils and gcc with --with-sysroot, but 
this doesn't help.

Anyone any ideas? Is this a gcc problem, a binutils problem, or a uClibc 
problem ? Any ideas how to solve

Thanks in advance,

David.
