Not really, I made this package for a local python-efl package when it's fetched
from the git repository and I was able to use it.
Cython is used to regenerate some C files, it's not used to build a target binary.

However, I tried to enable cython support to libplit as an example, but it
doesn't build when a cross compiler is used.
It use the host-python to build a binary for the target using the cross-compiler...

Also there is a m4 macro AC_PYTHON_DEVEL which can't be used with a
cross-compiler. It also try to link a C test program with host-python library
using the cross-compiler.

Here is the error:
"#error "LONG_BIT definition appears wrong for platform (bad gcc/glibc config?).

I don't think it's "fixable"...

There was another proposal for host-cython (I missed it):
http://patchwork.ozlabs.org/patch/477500/

So there is some rare case where cython can be used... but I don't know if there
is another package in Buildroot which can use it.

Thanks!

Best regards,
Romain
