Makefile: provide a target to build object files only
This would be especially useful when link time optimization is
enabled, as in that case the linker does not operate properly on
archives, separate object files are required.
Also, prevent multiple execution of string substitution function when
deriving lists of object and dependency file names from source file
names.
BRANCH=cr50, cr50-mp
BUG=b:65253310
TEST=Cr50 image builds fine with object files produced when using the
new make target during build
