Alexey Brodkin 2d4e2e238a binutils: fix building of Linux kernel for ARCv2 ISA 
With the fix for missing .tdata/.tbss sections we unintentionally
introduced a regression for ARCv2 ISA (read ARC HS38) kernel building.

That's what we got on attempt to build kernel:
----------------------------------->8--------------------------------------
  LD      drivers/video/fbdev/built-in.o
arc-linux-ld: ERROR: Attempting to link drivers/video/fbdev/omap2/built-in.o with a binary drivers/video/fbdev/built-in.o of different architecture
arc-linux-ld: failed to merge target specific data of file drivers/video/fbdev/omap2/built-in.o
scripts/Makefile.build:337: recipe for target 'drivers/video/fbdev/built-in.o' failed
make[3]: *** [drivers/video/fbdev/built-in.o] Error 1
scripts/Makefile.build:403: recipe for target 'drivers/video/fbdev' failed
make[2]: *** [drivers/video/fbdev] Error 2
scripts/Makefile.build:403: recipe for target 'drivers/video' failed
make[1]: *** [drivers/video] Error 2
Makefile:944: recipe for target 'drivers' failed
make: *** [drivers] Error 2
----------------------------------->8--------------------------------------

The reason was empty .tdata and .tbss sections in empty archives. And
later empty archives were linked in built-in.o with default architecture
(in our case ARCv1 ISA, read for ARC 700) and then expected failure
happened when objets for different architectures were attempted to link
together.

Now we have a fix for that issue, see
a65b844aed

This fix is in arc-2.23-dev branch and will be a part of the next
release of ARC tools, so then this patch must be removed from buildroot.
