[patch] enable speed vs size option for md5sum

[walter harms]

Hello list,
some time ago i ask about the size vs speed option in md5sum.
this patch will make the option available via menuconfig.
It contains only a fix for hash_fd.c to remove the current define.
Only the coreutils/Config.in is changed also.
the data are directly from the source code.

re,

I added the diff in attachment in case a mailer mangles it.
