Add support for a saving build objects in a separate directory. Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory. 2006-09-02 02:49:50 +09:00			`# (C) Copyright 2006`

powerpc: convert makefiles to Kbuild style Note: arch/powerpc/cpu/mpc8260/Makefile is originally like follows: ---<snip>--- START = start.o kgdb.o COBJS = traps.o serial_smc.o serial_scc.o cpu.o cpu_init.o speed.o \ ---<snip>--- COBJS-$(CONFIG_ETHER_ON_SCC) = ether_scc.o ---<snip>--- $(LIB): $(OBJS) $(call cmd_link_o_target, $(OBJS) $(obj)kgdb.o) The link rule `$(call cmd_link_o_target, $(OBJS) $(obj)kgdb.o)' is weird. kbdg.o is not included in $(OBJS) but linked into $(LIB) and $(LIB) is not dependent on kgdb.o. (Broken dependency tracking) So, START = start.o kgdb.o shoud have been START = start.o SOBJS = kgdb.o That is why this commit adds kgdb.o to obj-y, not to extra-y.
