Hi,

dosbox-x-2024.03.01 uses esfmu-v1.2 (https://github.com/Kagamiin/ESFMu)
library and it could not build on i386.

Current version of esfmu (v1.2.6) has fixed and I added necessary diff
to build dosbox-x-2024.03.01 port.

(simply picked https://github.com/Kagamiin/ESFMu/compare/0311b0d..0994f3e)

ok?
