Not sure whether an arch like is supposed to install headers at all, I guess no. :) Thanks, //richard

OpenWRT/LEDE patches for their build tree patch UML to do so when building UML. IMHO it is a hack, but it works.

We could install host-arch headers for UML if we like, but I am not sure whether is is sensible... Wait for comments in case somebody has a better solution.

Some samples require headers installation, so commit 3fca1700c4c3 ("kbuild: make samples really depend on headers_install") added such dependency in the top Makefile. However, UML fails to build with CONFIG_SAMPLES=y because UML does not support headers_install.
