examples/lora/build-RadioLib.sh: remove depenency on /bin/bash

…tom-toolchain

Remove custom RISC-V toolchain from Nix shell, remove Segger J-Link, update Tockloader to v1.11.0

This ensures that prior to building a C++ source file, both libc++ and
newlib are available. It fixes a race condition in the GitHub actions
CI which would fail by first building `examples/cxx_hello/main.cc`,
which proceeded to build it with neither newlib or libc++ fetched. We
make C++ objects depend on newlib as well, as they can feature
includes from the C standard library.

AppMakefile: depend on libc++ and newlib for cc,cpp,cxx build rules

Previous implementation overflowed an intermediate calculation when
computing the time in microseconds. This implementation resolves the
overflow and also provides comments and assertion statements to guard
against future overflow bugs.

Alarm overflow - gettimeasticks

I think Tyler just copied this wrong. I put in the version I was using.

This makes the commit hash used to build newlib and libcpp new enough to
include the full PR on libtock-c/master.

build(deps): bump express from 4.17.3 to 4.19.2 in /examples/courses/2018-11-SenSys/sensys_udp_rx/server

make: tocklib: fix debug comment

This fixes an issue when multiple Tock libraries are used in the same
build. With `?=`, the value is "reset" for each instantiation of
TockLibrary, causing the build directory for all libraries to be set to
whichever library is included last. With `:=` this does not occur.
