Does your arch's compiler support -ffuncation-sections and
-fdata-sections? As well as your linker supporting --gc-sections ? All
the architectures we support have those flags. See Makefile.inc which
provides those in CFLAGS_common and LDFLAGS_common. That support
allows us to not sprinkle #ifdef's all around in the code when the
same source file is compiled for different stages.
