From 3363179385629c1804ea846f4e72608c2201a81e Mon Sep 17 00:00:00 2001 From: Brendan Higgins Date: Fri, 24 Jan 2020 14:14:01 -0800 Subject: um: Make CONFIG_STATIC_LINK actually static Currently, CONFIG_STATIC_LINK can be enabled with options which cannot be statically linked, namely UML_NET_VECTOR, UML_NET_VDE, and UML_NET_PCAP; this is because glibc tries to load NSS which does not support being statically linked. So make CONFIG_STATIC_LINK depend on !UML_NET_VECTOR && !UML_NET_VDE && !UML_NET_PCAP.
