    x86: don't create MAINBOARDDIR/romstage.inc for !ROMCC boards
    
    Previously, the x86 romstage build process was unconditionally
    creating a romstage.inc and adding it to crt0s. This step is
    inherently not necessary in the !ROMCC case becaue the romstage.inc
    was created by the compiler outputting assembler. That means
    MAINBOARDDIR/romstage.c is truly a C environment that requires
    some sort of assembler stub to call into (cache_as_ram.inc from
    the chipset dirs). Therefore, remove this processing. The result
    is that MAINBOARDDIR/romstage.c can use the normal build steps
    in creating an object and linking. The layout of romstage.elf
    will change but that's only from a symbol perspective.
