Print the name of the discovered toolchain as well as the variable used to initialize it. This is nice to know when doing remote support, since users will sometimes misconfigure their toolchain and not know what that means. Signed-off-by: Martí Bolívar <marti.bolivar@nordicsemi.no>

# CROSS_COMPILE is a KBuild mechanism for specifying an external
|
|
# toolchain with a single environment variable.
|
|
#
|
|
# It is a legacy mechanism that will in Zephyr translate to
|
|
# specififying ZEPHYR_TOOLCHAIN_VARIANT to 'cross-compile' with the location
|
|
# 'CROSS_COMPILE'.
|
|
#
|
|
# New users should set the env var 'ZEPHYR_TOOLCHAIN_VARIANT' to
|
|
# 'cross-compile' and the 'CROSS_COMPILE' env var to the toolchain
|
|
# prefix. This interface is consistent with the other non-"Zephyr SDK"
|
|
# toolchains.
|
|
#
|
|
# It can be set from either the environment or from a CMake variable
|
|
# of the same name.
|
|
#
|
|
# The env var has the lowest precedence.
