[Buildroot] [PATCH 05/13 v2] core: simplify removal of generated br2-external files

[Yann E. MORIN]

Now that all the br2-external generated files are named after the same
pattern, it gets easier to remove them all using a glob.

Furthermore, we're on the verge of introducing more such generated
files, so removing them at one fell swoop will be simpler too.
