* Makefile.in (ALL_TARGET_OBS): Remove object files that require
64-bit CORE_ADDR and BFD support, move them to ... (ALL_64_TARGET_OBS): ... this new variable. * configure.ac: Check for --enable-64-bit-bfd option. Only add 64-bit targets with --enable-targets=all if BFD supports 64-bit. * configure: Regenerate. * i386-cygwin-tdep.c (i386_cygwin_osabi_sniffer): Do not claim all elf32-i386 executables, only cygwin core files.
