[Buildroot] [PATCH 1/1] package/bash: remove development files and modules on the target.

[Nicolas Cavallari]

bash installs /lib/pkgconfig/bash.pc on the target, which buildroot does
not remove because it is not in the usual /usr/lib/pkgconfig.

It also install makefiles and example builtins in /lib/bash that are not
required.

The Makefiles and .pc encode the build path and create reproducibility
issues.  Remove them.

I am wondering if target-finalize shouldn't take care of removing
/lib/pkgconfig just like it removes /usr/lib/pkgconfig. This would have
the benefit of also dropping the /lib/pkgconfig folder, which your
change doesn't do.

What do you think?

This would work too, but do we want to add things to target-finalize 
just for (apparently) only one little package ?
