Subject: [PATCH 06/12] selftests: lib.mk: Add rule to build object file from C source file

Currently there are rules to compile and link one or more C or
assembler source files into a full executable, and to assemble a single
assembler source into an object file.

Add a generic rule to compile a single C source file into an object
file, for reuse of object files in multiple executables.
