The new syscall table support for arm64 mistakenly used the system's
asm-generic/unistd.h file when processing the
tools/arch/arm64/include/uapi/asm/unistd.h file's include directive:
#include <asm-generic/unistd.h>
See "Committer notes" section of commit 2b5882435606 "perf arm64:
Generate system call table from asm/unistd.h" for more details.
This patch removes the committer's temporary workaround, and instructs
the host compiler to search the build tree's include path for the right
copy of the unistd.h file, instead of the one on the system's
/usr/include path.
It thus fixes the committer's test that cross-builds an arm64 perf on an
x86 platform running Ubuntu 14.04.5 LTS with an old toolchain:
$ tools/perf/arch/arm64/entry/syscalls/mksyscalltbl /gcc-linaro-5.4.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc gcc `pwd`/tools tools/arch/arm64/include/uapi/asm/unistd.h | grep bpf
[280] = "bpf",
