Compare these:
$ python3.9 -m sysconfig
Current installation scheme: "posix_prefix"
Paths:
data = "/usr"
include = "/usr/include/python3.9"
platinclude = "/usr/include/python3.9"
platlib = "/usr/lib/python3.9/site-packages"
platstdlib = "/usr/lib/python3.9"
purelib = "/usr/lib/python3.9/site-packages"
scripts = "/usr/bin"
stdlib = "/usr/lib/python3.9"
...
prefix = "/usr"
...
To this:
$ python3.10 -m sysconfig
Current installation scheme: "posix_local"
Paths:
data = "/usr/local"
include = "/usr/local/include/python3.10"
platinclude = "/usr/local/include/python3.10"
platlib = "/usr/local/lib/python3.10/dist-packages"
platstdlib = "/usr/lib/python3.10"
purelib = "/usr/local/lib/python3.10/dist-packages"
scripts = "/usr/local/bin"
stdlib = "/usr/lib/python3.10"
...
prefix = "/usr"
...
The "posix_local" scheme uses {prefix}/local/lib/... That's the issue.

This patch restores the previous (pre 3.10) behaviour. If you use --prefix
/usr, it installs modules to /usr, with --prefix /usr/local, it installs to
/usr/local.

I think it shouldn't affect users. If anything needs to be documented, it's:
Automake will select the posix_prefix scheme instead of posix_local, on Debian
Python 3.10+. To install modules into /usr/local, instead of /usr, use --prefix
/usr/local.
