[ptxdist] [PATCH v2] libgpiod: new package

[Clemens Gruber]

libgpiod is a C library with tools for interacting with the Linux
GPIO character device. Add a package for it.

Note: Requires kernel-headers >= 4.8.

This should have a changelog below the tripledash.

Right. Not sure if I should resend though, as the changelog will not
show up in the commit message.
Let me know if you want me to resend the patch with the changelog
anyway.

Changes since v1:
- Added the kernel-headers include directory to CPPFLAGS
- Added some warning notes/comments that >= v4.8 is required

Cheers,
Clemens

Is this a copy of the kernel's tools/gpio directory? If so, I'd prefer
to stick to the official source.

Best regards
Uwe

No.. it's a separate userspace library (and tools) to interact with the
GPIO character device.
