[discussion]
This is supposed to be a arm stable version. The only alternative left in the main portage tree is dev-python/pycrypto-2.0.1-r5 which shows the same problem. Possible patch needed to force checking $CHOST instead of assuming i686 toolchain? Possibility that the CROSS_COMPILE variable is not being passed properly? No immediate solutions with Gentoo bugs or Google.

Required for Gentoo systems.

Already patched offline, but I want to upload the patch here for documentation. Give me a day or two...
