8# may be needed by other classes and/or recipes. If you add a new
9# target this will probably need to be updated.

11#
12# Returns information about 'what' for the named target 'target'
13# where 'target' == "<arch>-<os>"
14#
15# 'what' can be one of
16# * target: Returns the target name ("<arch>-<os>")
17# * endianness: Return "be" for big endian targets, "le" for little endian
18# * bits: Returns the bit size of the target, either "32" or "64"
19# * libc: Returns the name of the c library used by the target
20#
21# It is an error for the target not to exist.
22# If 'what' doesn't exist then an empty value is returned
