It turns out that we have unistd.h for some architectures but not others. We are thus unable to use e.g. usefaultfd on these systems.
Fix up update-linux-headers.sh to make sure we get it for all architectures which have linux-headers/ (unfortunately this still does not mean "all linux systems"). Tested on x86 only. Pls consider merging this through the migration tree. Michael S.
