mk_dlo — Build a dynamically loadable object
MODULES="... compiler ..."
mk_dlo  DLO=name   options... 
Defines a target to build a C/C++ dynamically loadable object --
that is, an object suitable for loading with dlopen() or similar
functions at runtime.  On some systems, Darwin in particular, this
is not the same thing as a shared library.  See
compiler for a list of common options.
A libtool-compatible .la file will also be generated and is
the target which is placed in result.
