It looks good. Note that I'm saying it looks good from a formatting
point of view: I haven't checked the actual licenses.

This is probably a bit too verbose, what you proposed above as the
first solution looks sufficient to me.

The Buildroot manual normally explains what the formatting should be,
but it is very possible that some packages do not comply 100% with the
rules described in the manual (simply because those packages were added
before the rules were clarified in the manual).

Basically, the idea is that: a comma separates multiple licenses that
cover different parts of the package, with parenthesis to indicate what
component is covered by that license. The "or" statement is used when
the package is available under a choice of licenses (i.e you can chose
to use say the GPLv2 terms *OR* the MIT terms for the whole package,
for example).

The modifications look good to me. Thanks a lot!
