[Buildroot] [PATCH] libgpiod: bump version to v1.1

[Bartosz Golaszewski]

This is a minor release the main feature of which are the
object-oriented bindings for C++ and Python3. Other than that there's
a couple bug-fixes and minor improvements all around.

 Is there really a need to make these bindings optional? We try to avoid too
many Config.in options. So only if the bindings are relatively large on target
it's worthwhile to make them optional (more than, say 20% of libgpiod itself,
after stripping).

 If the bindings don't make it much larger, you can just move the dependencies
to the BR2_PACKAGE_LIBGPIODCXX condition in the .mk file.

 Same here of course.

The basic library and tools only require a libc and recent kernel
headers. I don't want users of very simple systems to carry all those
dependencies for C++ and Python if they're not using it.

You don't need to. You can make BR2_INSTALL_LIBSTDCPP an optional dependency. 
If it is defined, install the C++ binding. Same goes for Python. That is what 
Arnout suggests.

ifeq ($(BR2_INSTALL_LIBSTDCPP),y)
... enable the build/installation of C++ bindings
endif

ifeq ($(BR2_PACKAGE_PYTHON),y)
... enable the build/istallation of Python bindings
