re PR bootstrap/14760 (A bug in configure{,.in} prevents using both --program-suffix and --program-prefix)

	offending options.  Also, don't match/substitute the trailing space,
	so that this actually works when two similar options are separated by
	only one space.

        compiler entries. Modify the "@c" compiler entry for doing IMA
        properly with "-save-temps" and the "combine" flag.

        to pass multiple input files to compiler at one time.
