1# This class exists to provide information about the targets that
2# may be needed by other classes and/or recipes. If you add a new
3# target this will probably need to be updated.
4
5#
6# Returns information about 'what' for the named target 'target'
7# where 'target' == "<arch>-<os>"
8#
9# 'what' can be one of
10# * target: Returns the target name ("<arch>-<os>")
11# * endianness: Return "be" for big endian targets, "le" for little endian
12# * bits: Returns the bit size of the target, either "32" or "64"
13# * libc: Returns the name of the c library used by the target
14#
15# It is an error for the target not to exist.
16# If 'what' doesn't exist then an empty value is returned
17#
