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

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

[ Upstream commit b523e185bba36164ca48a190f5468c140d815414 ]

This moves the DISABLE_BRANCH_PROFILING define from the x86 specific
to the general CFLAGS definition for the stub. This fixes build errors
when building for arm64 with CONFIG_PROFILE_ALL_BRANCHES_ENABLED.
