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" alonedoes not remove debug symbols). Moreover it seems thatllvm-strip, although it identifies as GNU strip, misbehaves whengiven "-x" for this purpose. It's unclear whether that'sintentional or a bug in llvm-strip, but in any case it seems likechanging to use --strip-unneeded in all cases should be a win.Note that this doesn't change our behavior when dealing withnon-GNU strip.Per gripes from Ed Maste and Palle Girgensohn. Back-patch,in case anyone wants to use llvm-strip with stable branches.Discussion:https://postgr.es/m/17898-5308d09543463266@postgresql.orgDiscussion:https://postgr.es/m/20230420153338.bbj2g5jiyy3afhjz@awork3.anarazel.de
