No, my understanding of the problem is that you cannot *compile* for
macOS unless you are on Apple hardware, ie no cross-compilation which
GUB is based on. This changed at some point in the past (many years
ago) and the software from before remains accessible, so GUB is able to
build for 32-bit.

You're a year late to the party, I already developed a proof-of-concept
last March: https://github.com/hahnjo/lilypond-binaries/ and I shared
this on the mailing list back then, see the thread starting at
https://lists.gnu.org/archive/html/lilypond-devel/2020-03/msg00337.html
Meanwhile, with the help of Erlend Aasland, the scripts also work on
macOS (at least they did last summer) and you get a fully relocatable
.tar.gz archive that you can unpack and run wherever you want.
