We could also probably cache based on (g)libc version, kernel version,
compiler & linker version, and any dependencies which gnulib modules may
use (e.g. OpenSSL).

While that might sound a bit much, it should be pretty quick to
calculate compared to no cache at all.

With that, you can do pretty well, I think. Whether or not it's worth it
is another question. We'd still need people to be responsible about it
(not use it recklessly, just when they're developing and know when their
system changes).

I wasn't aware of the Python tool work and am intrigued.
