AIX does not support undefined weak. Skip those tests in the testsuite.
Also, select COFF as AIX file format without requiring objdump.
* gcc.dg/attr-weakref-1.c: Skip on AIX.
* gcc.dg/torture/pr53922.c: Skip on AIX.
* lib/file-format.exp (gcc_target_object_format): AIX is COFF.
Bootstrapped on powerpc-ibm-aix7.1.0.0.
Thanks, David
