[patch] msp430: use custom libnosys.a
- From: DJ Delorie <dj at redhat dot com>

- Subject: [patch] msp430: use custom libnosys.a
- Authentication-results: sourceware.org; auth=none
Build msp430-specific libnosys. Committed.
The MSP430 debuggers support I/O on hardware through CIO, so
we can use a CIO-enabled library as the "nosys" library (in
addition to the libsim library, which talks to our simulator)
* configure.in: Don't build default libnosys for msp430
* configure: Regenerate.
* msp430/Makefile: Rename libcio to libnosys.
