I agree that Perl is fine. However, someone was suggesting getting rid of
the Perl scripts, apparently on the basis that Python can be "compiled"
with freeze; I pointed out that Perl can do the same.

Basically, I don't think trying to support compiling the kernel on a PC XT
using only MASM is a good idea - if you want to develop software, you need
some software tools.
