I doubt it has anything to do with my problem. If you take a look at
configure.in in libstdc++-v3, you can tell it tries to support cross
compile:

if test -n "$with_cross_host" || test x"$build" != x"$host"; then
...
  case "$target" in
    *-linux*)
    ...
fi

Unfortunately, it is far from complete. I don't think the rest of
libraries are any better, with the possible exception of libiberty.

It is "diff cross native".

I wish I were wrong. My impression is libraries in the current gcc
do not support cross compiling to Linux very well.
