>>> The problem is that "install" is run with "-s" argument to strip symbols but always uses default "strip" executable even in cross-compile mode. To fix the bug I check for the "strip" executable in the configure.ac and provide the result to the "install" command using "--strip-program" argument. The patches are attached to this email.

You'll notice the @apple.com in my email address right?

I actually tested this on Mac OS X. Looks like strip is only invoked for Release builds so my default build didn't catch it annoyingly enough.
