Subject: [PATCH 4.9 53/63] kbuild: set no-integrated-as before incl. arch Makefile

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

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

From: Stefan Agner <stefan@...er.ch>

commit 0f0e8de334c54c38818a4a5390a39aa09deff5bf upstream.

In order to make sure compiler flag detection for ARM works
correctly the no-integrated-as flags need to be set before
including the arch specific Makefile.

Fixes: cfe17c9bbe6a ("kbuild: move cc-option and cc-disable-warning after incl. arch Makefile")
