[PATCH v2 0/1] bfd: add a mean to programatically detect a release version

[Matthieu Longo]

In a recent discussion around Object Attributes v2 [1], it appeared that we needed a way to detect whether a tool was built as a release version, or development version.

A previous patch (7b40f4c6587c) introduced this detection in gas. This patch reuses the same principle but moved the code into a utility function in bfd, so that gas, ld, and others can rely on it. It also adds a Tcl function 'is_release' that can be used with a '#target: ' directive to disable some tests relying on development-only features.

Regression tested on aarch64-unknown-linux-gnu in my OAv2 branch.

Regards,
Matthieu.
