    AC_PROG_CC etc: avoid warnings when removing conftest* on OS X
    
    Reported by Nobuyoshi Nakada in:
    http://lists.gnu.org/archive/html/autoconf-patches/2013-03/msg00003.html
    * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CC_C_O, AC_PROG_CXX_C_O):
    * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O):
    * lib/autoconf/functions.m4 (AC_FUNC_SELECT_ARGTYPES):
    Use rm -rf, not just rm -f, when removing conftest*.
