Makefile updates

[nsaulnier-ti]

make all projects use ram-mode by default (double-check)

Do we want to make these AI suggested changes?

Refactor the makefile compile rule to explicitly specify the output object file
using --output_file=$@ and the source file using $<, improving build robustness
and preventing parallel build issues.

source/rpmsg/makefile [51-57]

 $(GEN_DIR)/%.obj: %.c
 	$(MKDIR) $(GEN_DIR)
-	@echo 'Building file: $^'
+	@echo 'Building file: $<'
 	@echo 'Invoking: PRU Compiler'
-	"$(CGT_TI_PRU_PATH)/bin/clpru" $(INCLUDE) $(CFLAGS) $(DFLAGS) $^
-	@echo 'Finished building: "$^"'
+	"$(CGT_TI_PRU_PATH)/bin/clpru" $(INCLUDE) $(CFLAGS) $(DFLAGS) --output_file=$@ $<
+	@echo 'Finished building: "$<"'
 	@echo ' '

Suggestion importance[1-10]: 6
__

Why: The suggestion correctly identifies a potential race condition with parallel builds and makes the makefile rule more robust by explicitly specifying the input ($&lt;) and output ($@) files for the compiler.
