Cross-building Haiku with Haiku host issues

[jessicah]

When trying to build an x86_64 Haiku image on a gcc2h Haiku host, I end up with an image that can't be booted by the haiku_loader. The error reported is "Version mismatch between boot loader and kernel!". I'm failing to see anything obvious in the jam logs that would indicate a problem with how the files are compiled. In order to build on Haiku, I use setarch x86 and run all commands in the gcc4 environment.

setarch x86
configure --build-cross-tools x86_64 ../buildtools --use-gcc-pipe -j4
jam -q -j4 @minimum-anyboot

I am also attaching a copy of the log generated by jam.

What about #8730?
