The test for the requirement of disabling wchar_t size warnings assumed
that $(CC) is used for linking, instead of $(LINK). With GCC $(LINK)
and $(CC) happen to be (in most cases) identical, but with LLVM they
are not. This results in issues with compiling with LLVM.
GCC on some platforms does need an executable stack to generate
trampoline code, but use of nested functions is not allowed in
RIOT's code base anyway.
This allows including C headers from C++. It sadly reduced the
diagnostics on C++ code as well, were there warning may make sense as
unintended side effect. We may be able to drop that later on, when more
C APIs are properly wrapped in native C++ APIs, so that C headers do no
longer need to be compatible with C++ compilers.
In an ideal world everyone would just install `gdb-multiarch` and be
happy. However, some MCUs need magic GDB versions sprinkled with
unicorn-stardust-Espressif-patches...
Since there is little reason to have `$(target)-gdb` installed in
addition to `gdb-multiarch` if `gdb-multiarch` would work fine, let's
assume the user wants to use `$(target)-gdb` when present over
`gdb-multiarch`.

Add USE_MODULE += "stdio_uart_onlcr" to enable it.
This is named after the "onlcr" stty flag, which does the same thing.

Model the LoRaWAN integration to GNRC's netif command (ifconfig) as
submodule of it, namely `shell_cmd_gnrc_netif_lorawan`.
This should fix a regression introduced by

When using podman instead of docker the registry is not set by default.
Docker has a builtin registry default "docker.io". Podman does not have a
default. By specifying the registry explicitly both tools can be used.
With RISC-V being a relatively young toolchain, a lot of inconsistencies
between different toolchains are to be found that differ in the target
triple and the flags supported. This build system performs run-time
tests to detect the toolchain and supported flags.
With `BUILD_IN_DOCKER=1` issues arise, as this checks are performed
outside of the docker container. However, the host may have no RISC-V
toolchain installed or a different toolchain, so there is little reason
in performing this detection then. Instead, a hard coded target triple
and supported flags are provided when using `BUILD_IN_DOCKER=1`.
If `AVRDUDE_PROGRAMMER` is already set to a programmer that is also
capable of debugging, we can assume that typically the user will want
to use the same hardware for debugging. Thus, let `AVR_DEBUGDEVICE`
default to the matching hardware.
