check for the presence of libiio to enable the compilation of
the bebop rangefinder that needs it.
If the build remains static, there needs to be a rootfs that contains
the libiio.a file because it is not included in the debian package.
A solution can be to compile libiio and copy libiio.a in /usr/lib[/arch]
Otherwise it fails to link:

It makes more sense the toolchain Waf tool to be responsible of loading the
compilers. Furthermore, that allows toolchain tool to have control on doing
configuration before and after loading compiler tools.
Two things are fixed with this patch:
1. We sort dictionaries' keys if they aren't OrderedDict instances. Since
dict objects don't guarantee order, environment variables may have contents
in wrong order, causing unnecessary rebuilds.
2. We only use prepend_value() if there's already a value set for the key
and that value is list. Before this change, boards couldn't set
non-iterable values.
Copy the missing warnings from AP_Common.h and reorder the warnings to
be more clear on intent. This will later let us remove the warnings from
the header.
Instead of a dictionary of dictionaries, have a dictionary of
ConfigSets. Using ConfigSet have two benefits: (1) allow easily copying
values from other, (2) have syntax for specifying the keys directly as
attributes.
With this change now it's easier to specify minlure without
repetition. New boards can override a value, append or prepend depending
on the need.
DEFINES attribute is treated as a dictionary instead of a list, so
that's easier to override values (at expense of ordering). When reading
the board environment, the code converts back to a list.
The board configuration is now stored in a separate file, there's also a
function to get the boards names.
