Having the build time written on stderr make it appear with V=w
although it is not an error or warning. Just write the time on stdout
to have it part of the build log like all the rest, but not clutter
the output when only warnings and errors should be shown.

(cherry picked from commit 340df72e07)
Use Time::HiRes when available and fallback to raw syscall interface
when not. If that fails too, simply report 0, 0 as real time.

Replace the GNU time program invocation with a simple Perl script reporting
the timing values. Since we require Perl anyway for the build system, we can
as well use that instead of requiring a random GNU utility rarely installed
by default.
