Conditionalize make behavior e.g. disable --gc-sections

[Peter Dufault]

What is best practice to change build behavior?  e.g. I need to use --whole-archive/--no-whole-archive in one place but --gc-sections breaks it and that's turned on for the BSP (xilinx_zynq_a9_qemu).

I’ve done this in the .cfg files for the BSP:

ifneq ($(RTEMS_GC_SECTIONS_DISABLE),1)
LDFLAGS_GC_SECTIONS_DISABLE = -Wl,--gc-sections
endif

(...)

LDFLAGS = $(LDFLAGS_GC_SECTIONS_DISABLE)

and then I set RTEMS_GC_SECTIONS_DISABLE=1 in the one Makefile where I need it.  I don’t see similar patterns, is this the way to do it?
