Subject: [PATCH 3.16.y-ckt 033/110] x86/vdso: Fix the x86 vdso2c tool includes

3.16.7-ckt13 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tommi Kyntola <tommi.kyntola@...il.com>

commit 0a4f59d6e09ef16fbb7d213cfa1bf472c7845fda upstream.

The build-time tool arch/x86/vdso/vdso2c.c includes <linux/elf.h>,
but cannot find it, unless the build host happens to provide it.

It should be reading the uapi linux/elf.h

This build regression came along with the vdso2c changes between
v3.15 and v3.16.
