Based on the file lists you sent in a followup post, it appears that
Ubuntu uses a different naming convention for these libraries, so
AC_SEARCH_LIBS will not find the function it needs in either libnl-3 or
libnl-genl-3, since they don't exist.

Is there a -devel package you can install that provides a pkgconfig
file for libnl-3?
