[coreboot] build service results for r5280

[coreboot information]

Dear coreboot readers!

This is the automatic build system of coreboot.

The developer "stepan" checked in revision 5280 to
the coreboot repository. This caused the following 
changes:

Change Log:
dependency tracking for coreboot

Obviously compile time increases slightly because more work has to be done, but
I'm sure the benefit of having to rm -rf build less often is worth it :-)

Other small changes:
* be a bit more verbose on some of the created files
* move -O2 from compiler rule into bootblock_romccflags
* drop rule needed for util/*.c -> build/*.o as x86emu no longer lives in util.

Build Log:
Compilation of soyo:sy-6ba-plus-iii is still broken
See the error log at http://qa.coreboot.org/log_buildbrd.php?revision=5280&device=sy-6ba-plus-iii&vendor=soyo&num=2


If something broke during this checkin please be a pain 
in stepan's neck until the issue is fixed.

If this issue is not fixed within 24h the revision should 
be backed out.

   Best regards,
