When we select a non-bx get_pc_thunk, we get an extra mov to set up
the PIC register before the abort call. Expect that mov or a
get_pc_thunk.bx call.
Regstrapped on x86_64-linux-gnu; also tested on i686-linux-gnu with
-fPIE. Ok to install?
for gcc/testsuite/ChangeLog
* gcc.target/i386/pr70321.c: Cope with non-bx get_pc_thunk.

More tolerance and less prejudice are key for inclusion and diversity
Excluding neuro-others for not behaving ""normal"" is *not* inclusive
