Move object files to $(obj)/<class>/ 

Instead of tagging object files with .<class>, move them to a <class>
directory below $(obj)/. This way we can keep a 1:1 mapping between
source- and object-file names.

The 1:1 mapping is a prerequisite for Ada, where the compiler refuses
any other object-file name.

Tested by verifying that the resulting coreboot.rom files didn't change
for all of Jenkins' abuild configurations.
