* defs.h (print_transfer_performance): Update prototype.
	* m32r-rom.c (m32r_load, m32r_upload_command): Use gettimeofday
	for print_transfer_performance.
	* remote-m32r-sdi.c (m32r_load): Likewise.
	* symfile.c (generic_load): Likewise.
	(report_transfer_performance): Create a dummy struct timeval.
	(print_transfer_performance): Use a more accurate measure
	of performance.
