OS X build broken: framework not found Foundation

[n13]

OS X 11.0 - Big Sur

I did the manual build steps as per the instructions since I have never gotten the brew install to work correctly

This used to work prior to OS X big sur, but it now fails with a build error

The below is the end of the output

Any ideas how to fix this would be appreciated.

I will append the full output as well eosio.cdt.build.log.txt

Big Sur has some changes as to how dynamic libraries are accessed.

Currently, Big Sur is not supported at this time. We will let you know when it is available.

This is even more problematic now that M1 Silicon macs are out and the brew package doesn't support silicon.

Any way to fix this?

Edit: Python has fixed this, it seems https://bugs.python.org/issue41100

eosio.cdt 1.7.0 is required to compile contracts for many EOSIO-based systems - is there an alternative way to install CDT 1.7.0? Brew seems to only have 1.8 built currently and these builds seem to fail.

For example, even if I run:

arch -x86_64 ./scripts/eosiocdt_build.sh

The build fails with:
