gst1-plugins-base fails to compile due to libs missing

[mlainez]

Environment

• Elixir 1.15.4
• Nerves system rpi4 1.27.0

I'm using WPEWebkit in weston using a drm backend in a custom system for rpi4.

Current behavior

When I select multimedia support for wpewebkit in buildroot, the system fails to compile gst1-plugins-base with the following errors:

../aarch64-nerves-linux-gnu/bin/ld: cannot find -lbrcmGLESv2
../aarch64-nerves-linux-gnu/bin/ld: cannot find -lbrcmEGL

When multimedia support and gstreamer is disabled, it succesfully compiles.

Expected behavior

It used to compile properly in previous versions (I recall it working on 1.25.1)

I moved to the unreleased nerves_system_br 1.27.1 and it is fixed. Must have been an issue in BR.
