Joe, I was reading the libtool archives today, and I think I have an
idea how they work now and might have an idea for a working hack.

Anyway, configure and ltmain.sh work together to generate the libtool
script at build time. ltmain.sh is generated by libtoolize and
libtool.m4 by the developer. But, you can patch it at build time like
Makefile.in. That way, you can force in options that libtool would
otherwise not know how to handle, like --sysroot.

For instance:

sed -i.bak 's%compiler_flags=$%&"--sysroot=/foo/bar"%' ltmain.sh

That would make the first empty compiler_flags have --sysroot instead.
For my boring old native compiler, it made things break, but you can
see that the option got in there.

/bin/sh ../libtool --tag=CC --mode=link gcc  -g -O2   -o
libpaco-log.la -rpath /usr/lib  libpaco_log_la-log.lo  -ldl
gcc -shared  .libs/libpaco_log_la-log.o  -ldl --sysroot=/foo/bar
-Wl,-soname -Wl,libpaco-log.so.0 -o .libs/libpaco-log.so.0.0.0

Does that help at all?
