This patch adds a number of tests for ARC target specific options.

I'm a bit uncertain here if I still need approval for this patch.
On the one hand the changes are all in an area that is normally within
the remit of a target maintainer, and patch to add the gcc.target/arc
directory has already been accepted.
OTOH, the man body of the ARC port is still stuck waiting for review,
so I'm still in the weird position of a target maintainer without an
accepted target port.

No, it is not required.  Target maintainers can approve the usual tests suite patches.  Everything in gcc.target/<target> certainly are in this set.  They typical changes to .exp for target supports for example are fine, as are the typical patches in existing test cases to declare things like small stacks, low memory, no common support, 16 bit porting, 32  bit porting and so on…  if in doubt, ask, we endeavor to be responsive to patches.

Though, technically, it should go in as the port goes in.  :-)

I did review the patch anyway, Ok.
