As discussed at the Google GCC gathering, disable the build of static libraries

libjava build isn't useful out of the box, and I don't see it packaged by Linux
distributions either.
The AC_PROG_LIBTOOL check is needed to get access to the enable_shared macro.
I'm unsure about the check in the switch construct. Taken from libtool.m4, and
determining the value of enable_shared_with_static_runtimes.
Ok for the trunk?

* Makefile.def (target_modules/libjava): Pass
$(libjava_disable_static).
* configure.ac: Check for libtool, pass --disable-static
in libjava_disable_static.
* Makefile.in: Regenerate.
* configure: Likewise.
My autoconf fu is not what it used to be. It is fine if static
libraries are disabled by default, but it should be possible to enable
them from the configure command line. It is unclear to me if this patch
does that.
Also I would like to go on record as disagreeing with the statement that
'static libjava build isn't useful out of the box'
