It is possible to produce a statically linked UML binary with UML_NET_VECTOR,
UML_NET_VDE and UML_NET_PCAP options enabled using alternative libc
implementations, which do not rely on NSS, such as musl.
Allow static linking in this case.

This option gives you the ability to force a static link of UML.
Normally, UML is linked as a shared binary. This is inconvenient for
