Nikodemus pointed out to me, and I discovered independently, that the
symptoms were caused by having stale build tools from an x86 build--in
particular, grovel-headers was built for x86, rather than x86-64. The
semi-obvious place where this really showed up is in FILE-WRITE-DATE
(once my build somehow stumbled into building contribs)--every file
had a FILE-WRITE-DATE of the epoch.
So, ./clean and rebuild, and everything is OK again.
