Changes from v3:
* restored FORBID_STATIC_LINK and renamed it to MAY_HAVE_RUNTIME_DEPS, so we
don't have to maintain a static list of options, which may produce runtime
dependencies
This is a continuation of [1]. 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.
