Thanks. I should have noticed that from the failing reprotest in the
Salsa CI, but did not look closely and thought that it would be due to a
different problem that has shown up on i386 since ncurses 6.3-1.

That works with umask 002, but in fact the file could have any
permissions from 000 to 666, depending on the umask used when the source
was unpacked.
I have installed a different fix, and now the reprotest succeeds
again[1].
