[Qemu-devel] [PULL 12/21] update-linux-headers: update for 4.11

[Peter Maydell <peter.maydell@linaro.org>]

From: Paolo Bonzini <pbonzini@redhat.com>

The linux-headers/asm-arm/unistd.h file has been split in three
sub-files, copy them along.  However, building them requires
setting ARCH rather than SRCARCH.

SRCARCH defaults to $(ARCH) anyway; to avoid future occurrence of
the same problem use ARCH for all architectures where SRCARCH=ARCH.
Currently these are all except x86, sparc, sh and tile.
