PR target/14548 * config.host: Set the shell variable host_can_use_collect2. Set it to yes by default, and to no for alpha*-dec-*vms*, i[34567]86-*-mingw32*, and powerpc-*-beos*. * configure.ac: Set and substitute the shell variable collect2. Give an error if use_collect2 is yes and host_can_use_collect2 is no. * Makefile.in (COLLECT2): Rename from USE_COLLECT2. Change all uses. Initialize to @collect2@. (STAGESTUFF): Remove $(USE_COLLECT2). * config/alpha/x-vms (USE_COLLECT2): Don't set. * config/i386/t-mingw32 (USE_COLLECT2): Likewise. * config/rs6000/t-beos (USE_COLLECT2): Likewise. * config/pa/t-pa64: Remove commented out USE_COLLECT2. * configure: Regenerate.
