Hmm, in which cases would that be necessary? I can only think of using a
OSELAS toolchain that contains a wrong md5sum in its ptxconfig, and that
would probably be reason to make a new toolchain release. In all other
cases, the ptxconfig is either nonexistent or the doesn't contain an
md5sum, resulting in an empty value, therefore the md5sum from the menu
would be needed as described above.
