The MSP430 linker contains emulations for old and obsolete MCU types. Since all MCUs now have their own specific linker script (courtesy of TI) there is no need for these emulations and so this patch removes them. * Makefile.am: Remove obsolete MSP430 emulations. * configure.tgt: Likewise. * emulparams/msp430all.sh: Likewise. * Makefile.in: Regenerate. 2014-01-28 12:25:48 +00:00			`ARCH=msp:14`
