Makefile: Avoid duplicate class suffixes in $(call src-to-obj) The build system uses the $(src-to-obj) function in multiple places to figure out the corresponding output object file for a certan source file, most importantly when generating the rule to build it. Usually this is pretty simple, but some odd cases are a little tricky... such as the auto-generated intermediary C files containing an array definition generated from an ASL file. These files have already been compiled per stage, so they contain the stage as a suffix and reside in the build directory (e.g. build/.../dsdt.ramstage.c). The previous $(src-to-obj) implementation just blindly appends the stage again and turns this into build/.../dsdt.ramstage.ramstage.o. This isn't very useful, so to avoid confusion this patch makes it strip additional stage suffixes for those intermediary files. This also fixes a bug with the ASL postprocessor, which didn't take this double suffix into account: it added build/.../dsdt.ramstage.o to ramstage-objs which should've been build/.../dsdt.ramstage.ramstage.o. This only worked by accident because make compiled the file with its implicit %.o: %.c rule instead. BRANCH=none BUG=chromium:466469 TEST=emerge-falco coreboot with the new make 4.1. Also build Falco and Veyron_Jerry with make -r -R to make sure there are no other accidental uses of implicit rules in our build system.
