When WITH_REPRODUCIBLE_BUILD=yes is set in src.conf(5), eliminate the
time, user, and host from the loader's version information. This allows
builds to produce bit-for-bit identical output.

Instead of repeating "%s, Revision %s" "(%s %s)" in each loader, just
create the full version string in vers.c

the temporary file to vers.c at the end of the script
The previous logic wrote out to vers.c multiple times, so the file
could be incorrectly interpreted as being completely written out
after one of the echo calls with recursive make, when in reality it
was only partially written.
Also, in the event the build was interrupted when creating vers.c
(small race window), it would have a leftover file that needed to
be cleaned up before resuming the build.
