Bug#1024859: change in the extention importation with 3.11

[PICCA Frederic-Emmanuel]

in order to debug this, I started gdb

set a breakpoint in init_module_scitbx_linalg_ext

then a catch throw and I end up with this backtrace

Catchpoint 2 (exception thrown), 0x00007ffff70a90a1 in __cxxabiv1::__cxa_throw (obj=0xb542e0, tinfo=0x7ffff72d8200 <typeinfo for boost::python::error_already_set>, dest=0x7ffff72c1290 <boost::python::error_already_set::~error_already_set()>) at ../../../../src/libstdc++-v3/libsupc++/eh_throw.cc:81

not crystal clear to me :)
