Subject: [PATCH] Fix pyext_PATTERN for cross compilation

The pyext_PATTERN will add native arch as suffix when cross compiling.
For example, on qemuarm64, it is expanded to:
pyext_PATTERN ='%s.cpython-310-x86_64-linux-gnu.so'
which will result in the incorrect library name.

root@qemuarm64:~# find /usr/lib -name \*cpython\*

/usr/lib/libsamba-policy.cpython-310-x86-64-linux-gnu.so

/usr/lib/python3.10/site-packages/samba/gensec.cpython-310-x86_64-linux-gnu.so
[snip]

Set pyext_PATTERN to '%s.so' to remove the suffix.
