The old GCC ARM Embedded website on launchpad
(https://launchpad.net/gcc-arm-embedded) has been superseeded by the new
GNU Arm Embedded one
(https://developer.arm.com/open-source/gnu-toolchain/gnu-rm).
This also means a change of name from "GCC" to "GNU". Reflect this in
the enviroment variables so that the proper term is used henceforth.

Add initial support for NUCLEO-L073RZ board.
This is a typical Nucleo-64 board, so most files are reused
from already supported Nucleo boards with small changes.
