in rev. 1.57.  Fix this regression by making cc_tools a new-style

please see the gnu/usr.bin/cc/cc_tools/Makefile,v 1.52 commit log.

Caught this by accidentally touching param.h while in the process
of cross-buildworld for amd64.

amd64 world.  The csu code evalues this Makefile with a different origin.

(bogus, application name space) mcount function name on amd64.  Override
it here instead.

I've done it this way to avoid touching gcc source while 3.4 is in
progress, and this is the smallest, lowest impact I could come up with.
Adding a patch touches about 10-14 lines of Makefile, this touches only 1.
This will likely go away with the 3.4 import.

I spoke with Alexander about this a few days ago, but waited until after
sorting out some of the other bugs in the userland profiling.

Makeworld will add -static in the correct place if needed and possible.
Self-hosted builds can just use the system default.

Fixed some nearby style bugs (code unrelated to its comment, and comment
formatting).
