Add bootstrap for powerpc64 elfv2.
Because of issue with macros in precompiled.hpp, --disable-precompiled-headers is necessary.
Since openjdk compiles for elfv1 by default on big-endian ppc64, use a patch to compile for elfv2.
I assume here that GCC will be used exclusively on ELFv1 systems and Clang on ELFv2.

. Sort LIB_DEPENDS and USE_XORG
. Add a dependency in alsa-lib now that sound is supported on FreeBSD.
. Don't disable dtrace now that it is supported on FreeBSD.
. Less intrusive iconv change.
* Put MD specific include files (e.g. jni_md.h) in a subdirectory named
'freebsd' rather than 'bsd'. [1]
* Remove the necessity to always have /usr/local/include in the header
paths and linker paths. This allows jshell to use the system iconv.h
rather than the third party one and link correctly. [2]
* Fix getting process commands and arguments on FreeBSD.
* Bump PORTREVISION.
All fixes need forward porting to openjdk12.
