This allows to use unified asm syntax when compiling for the
ARM instruction. This matches documentation and seems what the
initial patch was intended doing when the flag got added.

This looks right to me and is the logic we had in GCC 5.
How has this patch been tested?
Can you please provide a ChangeLog entry for this patch[1].
Thanks,

For the avoidance of doubt, I mean that your patch is correct :)
(not that the existing code is right).

I've bootstrapped and tested this, together with your testsuite patch on arm-none-linux-gnueabihf
and committed both with r267804 with the following ChangeLog entries:
2019-01-10 Stefan Agner <stefan@agner.ch>
PR target/88648
* config/arm/arm.c (arm_option_override_internal): Force
opts->x_inline_asm_unified to true only if TARGET_THUMB2_P.
2019-01-10 Stefan Agner <stefan@agner.ch>
PR target/88648
* gcc.target/arm/pr88648-asm-syntax-unified.c: Add test to
check if -masm-syntax-unified gets applied properly.
Thank you for the patch. If you plan to contribute more patches in the future I suggest you
sort out the copyright assignment paperwork.
I believe this fix needs to be backported to the branches.
I'll do so after a few days of testing on trunk.
Thanks again,
Kyrill

Thanks for applying the patch! As far as I can see it did not made it
into the branch yet, do you think it can get backported there too?

Thanks for reminding me. I've now committed your patch and the test to the gcc-8 branch with r268764.
