MIPS: Repair Kbuild make clean breakage.

David Daney · ralfbaechle · commit ad4b2b627c8a · 2010-10-19T18:32:39.000+01:00
When running make clean, Kbuild doesn't process the .config file, so nothing generates a platform-y variable. We can get it to descend into the platform directories by setting $(obj-). The dec Platform file was unconditionally setting platform-, obliterating its previous contents and preventing some directories from being cleaned. This is change to an append operation '+=' to allow cavium-octeon to be cleaned.
