Yeah, I was going to suggest the same thing --- but not with that switch
name.  We already use enable/disable-largefile to control whether 64-bit
file access is built at all (this mostly affects pg_dump at the moment).

I think the clearest way might be to flip the sense of the variable.
I never found "LET_OS_MANAGE_FILESIZE" to be a good name anyway.  I'd
suggest "USE_SEGMENTED_FILES", which defaults to "on", and you can
turn it off via --disable-segmented-files if configure confirms your
OS has largefile support (thus you could not specify both this and
--disable-largefile).
