manylinux2014-aarch64 uses glibc version not in compliance with PEP599 #443
Description
In spec document, PEP599, the requirements to ensure the widest compatibility with the most distributions of Linux are described. It states:
If the wheel contains binary executables or shared objects linked against any allowed libraries that also export versioned symbols, they may only depend on the following maximum versions:
- GLIBC_2.17
However, the crosstool-ng configuration file for manylinux2014-aarch64 mentions glibc, version 2.25:
dockcross/manylinux2014-aarch64/crosstool-ng.config
Lines 301 to 306 in 2b8f043
Unfortunately, it's not as simple as modifying the configuration file to 2.17. If you do that, rebuilding the container results in this error:

I tried a few things to fix this error, including upgrading to the latest version of crosstool-ng, but I haven't been able to figure out how to fix it myself.
