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 https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/commit/a65b844aed9153789356e098984452df2f5d9058 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.
