--strip-unneeded could potentially cause lots of undefined reference
errors on static libraries.  Shared libraries don't suffer this
because symbols are put into a special section which strip knows not
to touch.

General rule of them:

binaries: strip <file>
static libraries: strip --strip-debug <file>
shared libraries: strip --strip-unneeded <file>
