I am attempting to package the Python module cx_Freeze for OpenWrt. I have written the Makefile (included below) and am comfortable with how it works and what I've defined (it's my understanding that Build/Compile/PyMod will effectively run setup.py with the toolchain's compiler setup).
When trying to build cx_Freeze (as part of the usual make world job), it fails when linking to python2.7 claiming that there are undefined references __isnan, __isinf, __finite, and __rawmemchr. I have included the full error listing below.
I have cleaned the buildroot, and gone as far as recompiling the entire toolchain. I have also tried multiple architectures (specifically x86 and brcm2708), only to get the same error. I have no problems building any other Python package - it seems the differentiator is cx_Freeze attempting to link against Python itself.
Switching the C library to glibc works, however I would like to support the default C library, musl, as well.
Please let me know if I can provide any more information about the host system or any additional context around the problem.

cx_Freeze is a set of scripts and modules for freezing Python scripts into executables, in much the same way that py2exe and py2app do.
