bfin, msp, and score all used an extra parameter to genscripts.sh
to select a "customizer_script" different from the standard one
named from the emulation. This patch renames the scripts to avoid
the need, tidying them in the process.

* emulparams/elf32bfinfd.sh: Update to suit.
* emulparams/: Delete.
* emulparams/msp430.sh: Rename from msp430all.sh. Remove
MSP430_NAME and msp430X vars.
* emulparams/msp430X.sh: New.
* emulparams/: Delete.
* emulparams/score3_elf.sh: Rename from scoreelf.sh. Remove
SCORE_NAME and score7_elf ARCH setting.

* Makefile.am (eelf32bfin.c, eelf32bfinfd.c): Update dependencies.
