So I could imagine two ways of doing this.  One would be a new file,
.config-fixed, that contains a series of "CONFIG_XXX=[ymn]" which
would have to be satisfied and which override what
allyesconfig/allnoconfig/randconfig would otherwise do.

The other way would be some kind of new tagging in the .config file
itself, e.g.:

CONFIG_64BIT=y	# FIXED


There are all sorts of interesting design questions hidden in here, of
course, including what if the fixedpoint declarations (whether done
via a separate file or via tags in .config) are mutually inconsistent.
