CI: Add a glibc symbol test as part of our per-PR tests

[leofang]

xref: conda-forge/cudnn-feedstock#97

We already use auditwheel repair when building our wheels, so maybe this is redundant. Setting this to P2 for now.

@carterbox WDYT?

I think it's good to either explicitly check glibc symbols or ensure that all of your build containers are using your oldest supported glibc and to know what that oldest supported version is.

It looks like auditwheel show is the one that does the glibc ABI checking.

Yeah we use cibuildwheel in the GHA to build wheels, and on Linux it does use the manylinux containers:

so my feeling is we don't have to do anything extra.
