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/python3.10/ -name tdb\*
/usr/lib/python3.10/site-packages/tdb.so
/usr/lib/python3.10/site-packages/tdb.cpython-310-x86_64-linux-gnu.so

Set pyext_PATTERN to '%s.so' to remove the suffix.
After the patch:
root@qemuarm64:~# find /usr/lib/python3.10/ -name tdb\*
/usr/lib/python3.10/site-packages/tdb.so

Upstream-Status: Inappropriate [embedded specific]
