I hope this does it. I suspect there's some sort of portability issue
with '<<<' redirection, though it worked for me on this Gentoo using
make-3.81 and bash-3.2_p33.
As for using it, I needed to compile a 32-bit binutils and add proper
LIBS '-L' flags to the command-line as well. You can get such a binutils
by compiling it with '-m32' among CFLAGS.
Cheers,
Eduard
