aix: Remove AIX 6.1 support.
AIX 6.1 is past end of life and extended support. This patch removes the configuration option and references to AIX 6.1. contrib/ChangeLog: * config-list.mk: Remove rs6000-ibm-aix6.1. Rename rs6000-ibm-aix7.1 to powerpc-ibm-aix7.1. Add powerpc-ibm-aix7.2. gcc/ChangeLog: * config.gcc (powerpc-ibm-aix6.*): Remove. * config/rs6000/aix61.h: Delete.
