Objcopy generates huge binary file

[rushire]

ARM arch, Linaro GCC 5.3-2016.02
objcopy target generates ~400Mb binary file, ending by section .note.gnu.build-id
$ objdump -x images/antares.elf

  0 .note.gnu.build-id 00000024  20000000  20000000  00020000  2**2
  1 .isr_vector        000001d0  08000000  08000000  00010000  2**0

Currently workaround is patching antares/toolchains/gcc.mk:

-OBJCOPYFLAGS+=-Obinary
+OBJCOPYFLAGS+=-Obinary -R .note.gnu.build-id

Another way is completely disable build-id section generation by --build-id=none compiler option

This sounds a lot more like a toolchain problem, I'll have a look in the evening and see if I can reproduce it with crosstool-ng-based toolchain.
