[Buildroot] failure to build gtk because of glib-genmarshal being built for target not host

[shaleh at speakeasy.net]

I am trying to build on x86 for x86. As mentioned in the subject, glib2's glib-genmarshal is built againt uclibc which prevents it from running during the build process. This tool is needed only for compilation and not released systems.

Looking at the log, it appears that glib's configure script correctly determined that a cross-compile was happening. Anyone know what went wrong? Or a resource discussing the issues surrounding compilation of glib2, gtk and friends in a cross-compilation environment?
