--- Comment #4 from Carlo Marcelo Arenas Belón <carenas@???> ---
Is this implying that macOS 11/arm64 won't be able to use the standard
allocator because its libc doesn't allow mmap calls that have both PROT_WRITE
and PROT_EXEC privileges even when using the (undocumented) MAP_JIT flag and
the application has been properly signed/notarized?

care to provide a link to relevant documentation, and why it is not a concern
for macOS 11/x64?

patch is changing generated files (aclocal.m4, configure) and should probably
be simplified, as well as making sure it also supports cmake correctly. FWIW
changes in the sljit subdirectory are usually done first upstream[1] and
propagated from there
