cygwin.h (SUBTARGET_SWITCHES): Add -mconsole; fix -mno-nop-fun-dllimport and minor doc fixes.

        * i386/cygwin.h (SUBTARGET_SWITCHES): Add -mconsole; fix
        -mno-nop-fun-dllimport and minor doc fixes.
        (STARTFILE_SPEC): Cygwin DLLs don't have dllcrt0.
        (LINK_SPEC): Add -mconsole support.
        * i386/mingw32.h (LIB_SPEC): Make libraries consistent with
        Cygwin.
        (LINK_SPEC): Remove. Use Cygwin's version.
        (MATH_LIBRARY): Make it null.
        * i386/crtdll.h (MATH_LIBRARY): Likewise.
