linux-yocto/5.0: fix system tap for arm
Integrating Richard Purdie's kernel patch to fix systemtap on arm:
[
arm/Makefile: Fix systemtap
Currently systemtap fails to operate correctly on armv7 systems such as beaglebone and
soon, qemuarm.

/tmp/ccaE9CMG.s: Assembler messages:

/tmp/ccaE9CMG.s:52: Error: architectural extension `mp' is not allowed for the current b
(which was from running the stap command with -v -v -v -k and then being able to run the command individually)
Note that it says armv5t above.
That comes from the code this patch changes
root at qemuarm:/usr/src/kernel# gcc -march=armv7-a /tmp/staptcNU6M/stap_4321_aux_0.c
cc1: error: -mfloat-abi=hard: selected processor lacks an FPU
which makes me wonder if cc-option fails unless -mfpu-vfp is on the commandline too.
Since we have a gcc which accepts the armv7-a arch, just remove the cc-option
wrapper unconditionally here.
