[Buildroot] [git commit master 1/1] linux: strip installed modules

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=8101c9a357d110d7b9055fc13e77f9775ea1b1e6
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The installed kernel modules should have useless build cruft stripped out
of them.  On my system, a default build went from a very unreasonable 30MB
to a normal 3MB (on disk) and from 14MB to 3MB when compressed due to the
info stored in the kernel modules alone.

[Peter: don't hardcode binutils strip specific options]
