I've added a makefile and man page for gcov, a GNU
code-coverage/basic-block profiler which is included with egcs; the
makefile went in a couple days ago; the man page should turn up in the
next sup scan.

egcs already supports generating instrumented object files; we were
only missing support for formatting the statistics for human
consumption.

See the man page (which i just wrote from scratch) or the info page
inside the gcc info file.  It appears to work on the arm32 and i386
ports; I haven't tried any others.
