# @DESCRIPTION:
|

# The toolchain-funcs aims to provide a complete suite of functions
|
||||
# for gleaning useful information about the toolchain and to simplify
|
||||
# ugly things like cross-compiling and multilib. All of this is done
|
||||
# in such a way that you can rely on the function always returning
|
||||
# something sane.
