Can I have shell access on a FreeBSD machine ?

Temptative patch (although hiding a probable issue with multi-process make under the carpet): ​https://github.com/postgis/postgis/pull/709

[strk]

I cannot reproduce the problem with an interactive shell in ​https://cirrus-ci.com/task/4695039455526912

[Sandro Santilli <strk@…>]

In 03cc059/git:

Do not assume .tmp file exists upon removal

CirrusCI is failing not finding the file.
Chances are multi-process make is building the same
file multiple times and thus not finding it upon removing it

A better fix would be useful (serializing those commands?)

Should fix #5250
