mpd: enable package for external ARC toolchain

Now using prebuilt arc-2017.09-rc1 toolchain it is possible to
build mpd package. The GCC patch solving the problem with pthread
support check now is the part of ARC toolchain.

Note this patch has a prerequisite that updates ARC prebuilt toolchain,

 In this case you should send the patches as a series. And if you don't, such a
comment should be below the --- line because it's not something that should stay
in the history.

The ARC prebuilt toolchain is not tested by our autobuilders. The two
ARC configurations that we have are:

support/config-fragments/autobuild/br-arc-full-internal.config
support/config-fragments/autobuild/br-arcle-hs38.config

The first is a Buildroot internal toolchain, the second is an external
toolchain, built with Buildroot.

So we are not testing the Synopsys-provided pre-built toolchain, and
therefore the build failures that were detected in mpd and vlc were not
caused by Synopsys pre-built toolchain.

Best regards,

Thomas

Indeed, so then that note about prerequisite makes no sense.
Evgeniy will resend this patch with fixed commit message shortly.

As was pointed out in the comments, this is only applicable once the
ARC external toolchain has been updated. So could you please send both
patches as a patch series, once the final version of the 2017.09 ARC
external toolchain is available?

In the mean time I'll mark the patch as Changes Requested in patchwork.

Thanks!

Thomas
