i think this is something to do with --with-sysroot.
Try removing the sysroot but i am not sure well sysroot/lib should
contain libc.so
/lib/libc.so.6 is provided by glibc whereas /usr/lib/libc.so is
provided by glibc-devel.
Maybe some one experienced can help you out.

I think works, creating extra library simlinks allows the build process to see
them.
i.e.
linking
libc.so -> libc.so.6
Allows the build process to find libc.
My question is, why is this necessary?
libc.so.6 is already a simlink to libc-2.3.2.so
Why doesn't the compiler recognize libc.so.6 as libc.so? This is the name of
the simlink in the /lib directory of my target and host, and I don't see any
simlinks to it.
Why is this step required? Should I being doing something "cleaner"
thx,

You have to copy the symlinks also cp -pf or do a tar
