roms: seabios: Rename CROSS_COMPILE to CROSS_PREFIX

SeaBIOS introduced CROSS_PREFIX in 2013 but it's not set in roms
Makefile.

With the change it's possible to cross-compile SeaBIOS on macOS,
if acpica/iasl is installed:
  cd roms
  export PATH=/path/to/cross/x86_64-unknown-linux-gnu/bin:$PATH
  make bios system=unknown-linux-gnu
