Невозможно скомпилировать ядро ​​Linux v4.14 на Debian Wheezy x86

Question

При компиляции Linux v4.14 (например, v4.14.10) в Debian GNU / Linux 7 (wheezy) он останавливается со следующим сообщением об ошибке:

./system/buildroot-2017.08.x/output/host/usr/bin/x86_64-buildroot-linux-uclibc-ld \
      -m elf_x86_64 -r -o vmlinux.o --whole-archive built-in.o \
      --no-whole-archive --start-group lib/lib.a arch/x86/lib/lib.a \
      --end-group
built-in.o: member arch/x86/kernel/head_64.o in archive is not an object

В Kernel v4.13 компиляция работает нормально.

    x86/unwind: Make CONFIG_UNWINDER_ORC=y the default in kconfig for 64-bit

    commit fc72ae40e30327aa24eb88a24b9c7058f938bd36 upstream.

    The ORC unwinder has been stable in testing so far.  Give it much wider
    testing by making it the default in kconfig for x86_64.  It's not yet
    supported for 32-bit, so leave frame pointers as the default there.

Отключение CONFIG_UNWINDER_ORC исправляет компиляцию в Debian Wheezy.
