BSD: Do not require dlfcn.h to build shared libs (#13573)

Remove ancient checks left from commit f5d95fb0 (Complete rework of
makefile generators expect trouble, 2002-11-08).  Modern FreeBSD and
NetBSD platforms support shared libraries.  When cross-compiling the
/usr/include/dlfcn.h may not exist on the host but the toolchain still
supports shared libraries.
