[dpdk-dev] [PATCH] devtools: avoid config backup during test build setup

[Thomas Monjalon]

The config options are updated with sed and the short inline option.
In FreeBSD, the suffix argument of the inline option is mandatory.
In order to avoid creating a backup file when using sed inline,
the argument is set as an empty suffix.

The short option '-i' does not expect '=' before the suffix argument,
so it understands '=' as the file suffix.
As a consequence, a backup file named '.config=' was created
in the build directory.

Removing the '=' sign while keeping an empty suffix
avoids creating a backup file.

Fixes: 4a4a20c4775b ("devtools: support FreeBSD")

This patch does not work on FreeBSD.
Does it mean the equal sign is required on FreeBSD?
This is not what I see on the documentation:
