That is by far the most common case, so providing a handy
shortcut for that case is a very sensible thing to do.

However, in that case the first approach ("make CROSS=i686-pc-mingw32-")
would still work, wouldn't it?

    make CROSS=/path/to/toolchain/bin/
or:
    make CROSS=/path/to/toolchain/bin/i686-xx-yyy-

And in the end, zlib's CROSS_PREFIX is exactly that, isn't it?
