Do you mean the extension is wrong, or that the build process is wrong?
I've looked at the code in question and there are very few platform-specific
differences.

We have internal mechanism to handle build-os != target-os, but nobody
used it so far, so no wonder that gcc or shared library might be still
looking at build os. Just report the particular issues you run into
and I'll try to address them when I get back home on Monday.
