This causes testsuite build failures with GCC 13, which doesn't support 
-mno-lsx.  I think you need to have a configure test for support for this 
option, while GCC 13 is supported for building glibc for this 
architecture.  (We're not ready to move to GCC 14 as the default in 
build-many-glibcs.py because of the hppa build failures there which still 
need to be understood / fixed.)
