roms/Makefile builds seabios for qemu and copyes bios.bin to pc-bios/.
Needs to be updated to also copy the acpi tables.  acpi tables must be
committed (like pc-bios/bios.bin, this is done for non-x86 hosts which
can't easily build x86 bios btw).  "make install" must be updated to
also install the acpi tables.  pc_piix.c should load them from disk and
stick into fw_cfg.
