FTBFS on master + imx_v7_defconfig

[Uwe Kleine-König]

Hello,

current master + imx_v7_defconfig fails to build for me when using
out-of-tree building:

	  LD      .tmp_barebox1
	arch/arm/lib/built-in.o: In function `unwind_init':
	:(.text.unwind_init+0x24): undefined reference to `__start_unwind_idx'
	:(.text.unwind_init+0x28): undefined reference to `__stop_unwind_idx'
	arch/arm/lib/built-in.o: In function `unwind_frame':
	:(.text.unwind_frame+0x264): undefined reference to `__start_unwind_idx'
	:(.text.unwind_frame+0x26c): undefined reference to `__stop_unwind_idx'
	:(.text.unwind_frame+0x270): undefined reference to `__stop_unwind_idx'
	/home/ukl/gsrc/barebox/Makefile:662: recipe for target '.tmp_barebox1' failed
	make[2]: *** [.tmp_barebox1] Error 1
	Makefile:123: recipe for target '_all' failed
	make[1]: *** [_all] Error 2
	Makefile:14: recipe for target 'all' failed
	make: *** [all] Error 2

bisect points to:

	0ec6488501b0 (kbuild: remove redundant -include include/generated/autoconf.h)

Best regards
Uwe
