Cannot build 1.4 release branch

[eschnett]

There was an update to the Julia 1.4 release branch recently. After pulling the update I see this error:

$ make
Traceback (most recent call last):

The file name has two consecutive dots, which looks suspicious.

Maybe #35653 ? #35849 backports that to 1.4.

[eschnett]

Yes, #35849 should correct it. (I'm testing a very similar patch locally.)

The recent commits corrected this problem.
