[Bug libgcj/24125] New: use dlmopen to avoid copying .so

["tromey at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Currently, SharedLibHelper will make a copy of a .so in some situations.
Specifically, this happens if the .so has already been opened by a
different class loader.

On systems that support it, we could (perhaps) use the dlmopen() call to avoid
this copy.  This would be more efficient.  Note that this comes from Solaris
but has recently been implemented in glibc; it appears in FC4.
