 The x86_64 toolchain currently fails to build.

 The first build failure appears to be a
 [http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43328 problem] with GCC's
 build system: it defaults to having multilib enabled, but if it is
 explicitly enabled with --enable-multilib as Haiku's build script does,
 the build fails. The patch to Haiku trunk removes --enable-multilib for
 the x86_64 target, I'm not sure if this issue affects the other targets
 that specify --enable-multilib.

 A second build failure occurs due to the use of the TARGET_64BIT
 definition in preprocessor conditionals in the haiku64.h configuration
 file for GCC, as it is no longer a compile-time constant. The patch to
 buildtools fixes this, and also includes some other changes I made to the
 x86_64 target definition to be more correct.
