Follow up to the discussion on the last version bump.
zmq does not (try to) detect these features when cross compiling,
so we must assist.
Output of prepare stage contains this now:
checking whether EFD_CLOEXEC is supported... (cached) yes
…
checking whether SOCK_CLOEXEC is supported... (cached) yes
checking whether O_CLOEXEC is supported... (cached) yes
checking whether SO_BINDTODEVICE is supported... (cached) yes
checking whether SO_KEEPALIVE is supported... (cached) yes
checking whether TCP_KEEPCNT is supported... (cached) yes
checking whether TCP_KEEPIDLE is supported... (cached) yes
checking whether TCP_KEEPINTVL is supported... (cached) yes
checking whether TCP_KEEPALIVE is supported... not during cross-compile
checking whether SO_PRIORITY is supported... (cached) yes
checking whether getrandom is supported... (cached) yes

Notes:
v3:
- Added s-o-b
v2:
- also enable getrandom(2)
- reorganize comments to reflect glibc follows kernel,
so years are not swapped
