* configure.in: Use RTEMS_PROG_CC_FOR_TARGET([-ansi -fasm]), adapt
        bspopts.h handling to other sh-BSPs.
        * include/.cvsignore: Add stamp-h*, bspopts.h*.
        * include/Makefile.am: Use include_HEADERS instead of H_FILES.
        * startup/bspstart.c: Reworked, based on the amos BSP.
