Firstly gmp, mpfr, and mpc do not like this flag obviously since they do not have the musl settings patched in so i cant compile with the musl wrapper because i cannot include those math libraries and when i try to prebuild them and use the flag --with-mpfr=/target/location it errors out saying it cant find any compatible versions of these libs/headers. that brings me to compiling without the musl wrapper but with --host=i686-linux-musl and that does work until you try to run the binary of gcc made static which gives the error cant execute or doesnt exist. Checking with ldd shows its static so the binary itself is corrupted in some way. My question now becomes, what would be the troubleshooting steps to see how its broke if possible?
