Unless I am mistaken, the text quoted below from README no longer reflects
the current behavior.
The text appears to be the same in master and v1.8.

--with-libltdl(=value)
This option specifies where to find the GNU Libtool libltdl support
library. The following values are permitted:
internal: Use Open MPI's internal copy of libltdl.
external: Use an external libltdl installation (rely on default
compiler and linker paths to find it)
<no value>: Same as "internal".
<directory>: Specify the location of a specific libltdl
installation to use
By default (or if --with-libltdl is specified with no VALUE), Open
MPI will build and use the copy of libltdl that it has in its source
tree. However, if the VALUE is "external", Open MPI will look for
the relevant libltdl header file and library in default compiler /
linker locations. Or, VALUE can be a directory tree where the
libltdl header file and library can be found. This option allows
operating systems to include Open MPI and use their default libltdl
installation instead of Open MPI's bundled libltdl.
