Since I was able to produce a working UML binary with UML_NET_VECTOR linked with musl with the changes included in the patches here. I was compiling on Arch Linux, so hopefully all the latest versions of the compiler, libraries and binutils. I also tested allyesconfig with both musl and glibc. The compilation succeeds with both, however both binaries (glibc one being dynamically linked) segfault on start. This is probably of some incompatible config option/module being included and not related to musl/glibc.
