AIX supports "FAT" libraries containing 32 bit and 64 bit objects (similar to Darwin), but commands for manipulating libraries do not default to accept both 32 bit and 64 bit object files. While updating the AIX configuration to support building and running GCC as a 64 bit application, I have encountered some build libraries that hard code AR=ar instead of testing the environment. This patch adds AR_CHECK_TOOL(AR, ar) to configure.ac for the two libraries and updates Makefile.in to accept the substitution. 2020-05-23 David Edelsohn <dje.gcc@gmail.com> libcpp/ChangeLog: * Makefile.in (AR): Substitute @AR@. * configure.ac (CHECK_PROG AR): New. * configure: Regenerate. libdecnumber/ChangeLog: * Makefile.in (AR): Substitute @AR@. * configure.ac (CHECK_PROG AR): New. * configure: Regenerate.
