It replaces
make BOARD=iotlab-m3 info-debug-variable-NEWLIB_INCLUDE_DIR
/usr/bin/../lib/gcc/arm-none-eabi/7.2.1/../../../../arm-none-eabi/include/
with
make BOARD=iotlab-m3 info-debug-variable-NEWLIB_INCLUDE_DIR
/usr/arm-none-eabi/include
Without trailing slash and without relative '..' everywhere.
It also uses `realpath` instead of `abspath` to support Mingw32.
Some versions of Mingw32 abspath implementation has trouble working with
windows formatted path.
$(abspath "C:/A/B") returns "/C/CUR/DIR/C:/A/B" instead of "/C/A/B"
relpath does not have this problem, it does additional symlink resolution but is
not a problem.
Note: on windows it does not remove the trailing `/`.

Only keep lines that are indeed include path.
It also keeps newlines as they do not matter.
It fixes Mingw32 support where `grep '^\s'` is not working the same way.
It also handles some mac `sed` that do not support `\s`.
Ouput tested with:
make -C examples/hello-world BOARD=samr21-xpro info-debug-variable-COMPILER_INCLUDE_PATHS
# by also putting newlines for readability
Now:
/usr/bin/../lib/gcc/arm-none-eabi/7.2.1/include
/usr/bin/../lib/gcc/arm-none-eabi/7.2.1/include-fixed
/usr/bin/../lib/gcc/arm-none-eabi/7.2.1/../../../../arm-none-eabi/include
Before:
/usr/bin/../lib/gcc/arm-none-eabi/7.2.1/cc1 -E -quiet -v -iprefix /usr/bin/../lib/gcc/arm-none-eabi/7.2.1/ -isysroot /usr/bin/../arm-none-eabi -D__USES_INITFINI__ /dev/null
/usr/bin/../lib/gcc/arm-none-eabi/7.2.1/include
/usr/bin/../lib/gcc/arm-none-eabi/7.2.1/include-fixed
/usr/bin/../lib/gcc/arm-none-eabi/7.2.1/../../../../arm-none-eabi/include
When NEWLIB_INCLUDE_DIR is set from other parts than 'COMPILER_INCLUDE_PATHS' it
does not have a trailing slash.
Also, it makes it more problematic when supplying it from the command line.
And anyway having two '/' does not break anything.
Not all users register their user in the docker group and should not run the
whole make process as root to use docker.
They can now overwrite DOCKER with `DOCKER="sudo docker"`.
Creating files as a user is correctly handled as `id -u` is still run as the
original user.
In the previous state, with llvm and arm for example, newlib-nano include dir
NEWLIB_NANO_INCLUDE_DIR is placed after NEWLIB_INCLUDES and so the default
'newlib.h' is used instead of the nano version.
The excluded patterns can always be defined as they only set `CFLAGS` that
should not be passed to `CXX`.
This prepares for replacing the cflags support detection by a function.
BUILDDEPS are files / make targets that should be build before compiling.
It can include packages source download, generating headers, modules.
It is the equivalent of `APPDEPS` but not limited to the application.
It cannot be done right now with `APPDEPS` as it is used in `BASELIBS` and
fixing it requires changing mips using it for source files.
The sensor family SHT10, SHT11 and SHT15 only differ in their accuracy (as in
calibration, not as in resolution). Thus, the same driver can be used for all.
The new driver name better reflects this fact.
I'm using something like this command for a while now for debugging
GNRC. Usually, I just patch it into the application I'm using it with,
but I think there is a benefit to also provide it to RIOT upstream
properly.
Add a target to print an internal variable value.
Usage: make info-debug-variable-VARIABLENAME
Example:
make info-debug-variable-ELFFILE

Skald is a very small and simple, TX-only BLE stack that supports
sending advertisements only. It is useful for building all kinds
of BLE beacons with very minimal memory footprints.
