# All the description above (and below) assumes <machine> is the
|
||||
# only data needed to control the build.
|
||||
# This is not always the case. So in addition to setting
|
||||
# MACHINE in the build environment we set TARGET_SPEC which is
|
||||
# composed of the values of TARGET_SPEC_VARS separated by
|
||||
# commas. The default is just MACHINE.
|
||||
#
|
||||
# If more that MACHINE is needed then sys.mk needs to decompose
|
||||
# TARGET_SPEC and set the relevant variables accordingly.
|
||||
# It is important that MACHINE be included in TARGET_SPEC_VARS
|
||||
# since if there is more the value passed as MACHINE will infact
|
||||
# be the TARGET_SPEC.
|
||||
# Note: TARGET_SPEC cannot contain any '.'s so the target
|
||||
# tripple used by compiler folk won't work (directly anyway).
