# LINKER_TYPE is the major type of linker. Currently binutils and lld support

# automatic detection.

# LINKER_VERSION is a numeric constant equal to:

# major * 10000 + minor * 100 + tiny

# It too can be overridden on the command line.

# These variables with an X_ prefix will also be provided if XLD is set.
