# This class exists to provide information about the targets that
# may be needed by other classes and/or recipes. If you add a new
# target this will probably need to be updated.
#
# Returns information about 'what' for the named target 'target'
# where 'target' == "<arch>-<os>"
#
# 'what' can be one of
# * target: Returns the target name ("<arch>-<os>")
# * endianess: Return "be" for big endian targets, "le" for little endian
# * bits: Returns the bit size of the target, either "32" or "64"
# * libc: Returns the name of the c library used by the target
#
# It is an error for the target not to exist.
# If 'what' doesn't exist then an empty value is returned
