The docs target generates docs directly into images. The directory in 
support is for temporary/intermediate files. Building to support and 
then just copy it all over to images seems like a waste of both time and 
disk space. Also note that the clean targets aren't mutually exclusive 
today. You can for example do clean-support or you can do clean-java.base.

Renamed to CONFIGURESUPPORT_OUTPUTDIR and put it in spec. Removed 
reference to make-support in configure and put the single use directly 
in spec.gmk.in instead. There is no need for configure to know about the 
sjavacservers dir. Changed dist-clean in Main.gmk to use the variable 
CONFIGURESUPPORT_OUTPUTDIR.
