This commit moves suffix rules from config.mk to scripts/Makefile.build, which will allow us to switch smoothly to real Kbuild. Note1: post/lib_powerpc/fpu/Makefile has its own rule to compile C sources. We need to tweak it to keep the same behavior. Note2: There are two file2 with the same name: arch/arm/lib/crt0.S and eamples/api/crt0.S. To keep the same build behavior, examples/api/Makefile also has to be treaked.
