compiling is broken when compiling against muslc

[Neo-Desktop]

basically its a gcc problem but the djgpp doesn't build under a muslc environment (and therefore alpine linux)

I had to include this patch for it to build correctly

https://gitweb.gentoo.org/proj/gcc-patches.git/tree/12.1.0/musl/50_all_calloc_libgccjit.patch?id=caa4485a49e1064181e7ac2df2c5476fbb6e9cf5

side note- I also prefer to use clang even though I'm not in a freebsd environment. The build script overrides both CC and CXX even if I pass it in as an environment variable.

the patches below remove the freebsd check and just override the script to use clang and clang++, this is obviously not necessary but it conforms to my usecase

this is the patch set I use to get it to compile correctly under alpine:
