The Build, Host and Target Concepts in newlib
=============================================
The build, host and target concepts are defined for gcc as follows:
build: the platform on which gcc is built.
host: the platform on which gcc is run.
target: the platform for which gcc generates code.
Since newlib is a library, the target concept does not apply to it, and the
build, host, and target options given to the top-level configure script must
be changed for newlib's use.
The options are shifted according to these correspondences:
gcc's build platform has no equivalent in newlib.
gcc's host platform is newlib's build platform.
gcc's target platform is newlib's host platform.
and as mentioned before, newlib has no concept of target.
`configure' options
