Use --strip-unneeded when stripping static libraries with GNU strip.

We've long used "--strip-unneeded" for shared libraries but plain
"-x" for static libraries when stripping symbols with GNU strip.
There doesn't seem to be any really good reason for that though,
since --strip-unneeded produces smaller output (as "-x" alone
does not remove debug symbols).  Moreover it seems that
llvm-strip, although it identifies as GNU strip, misbehaves when
given "-x" for this purpose.  It's unclear whether that's
intentional or a bug in llvm-strip, but in any case it seems like
changing to use --strip-unneeded in all cases should be a win.

Note that this doesn't change our behavior when dealing with
non-GNU strip.

Per gripes from Ed Maste and Palle Girgensohn.  Back-patch,
in case anyone wants to use llvm-strip with stable branches.
