#
# GO_EXTLINK_ENABLED: Set to 1 to invoke the host linker when building
# packages that use cgo.  Set to 0 to do all linking internally.  This
# controls the default behavior of the linker's -linkmode option.  The
# default value depends on the system.
#
# GO_LDSO: Sets the default dynamic linker/loader (ld.so) to be used
# by the internal linker.
#
# CC: Command line to run to compile C code for GOHOSTARCH.
