# 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.

# This file may be included multiple times, but only has effect the first time.
