make installworld: btxld: No such file or directory [solved]

This post is just to inform others that run into this problem.

For years I have ran into this error while running 'make installworld':

There's several other mailing list posts that insist that build orders
are wrong or that the date/time is incorrect or off. I always had
strictly followed buildworld/installworld all while running ntpd. My
workaround was to 'make -C /usr/src/sys/boot/i386' before installworld
to avoid this issue, as others have done as well.

I realized this time that I was applying local patches to the tree
before buildworld, then reverting the patches before installworld. This
changed timestamps of various source files that forced the rebuild
during installworld. The real solution was to not revert the files until
after installworld and to not change the source tree in any other way
between buildworld/installworld.
