I don't think there are innate limitations.  Any platform that
supports running a Posix shell, GNU Make, a C99-compliant C compiler,
and a standard C library, will do.

Is there some specific question that you are interested in, or a
specific platform?  And also, what version of Emacs are we talking
about?  Versions before 27 could have problems in the dumping process.

etc/MACHINES was relevant when Emacs included a special header file
for every platform it supported.  That system was tossed long ago, so
I don't think an exhaustive list is possible anymore, although in
principle such a list could be composed for a given time instance.
Even if prepared, such a list will quickly become outdated, as new
systems are created and old go into oblivion.
