'strip' does not normally preserve archive index in .a files.
This usually causes linking failures against static libs like:
$ nix build --no-link -f. pkgsCross.mingw32.re2c
> ...-i686-w64-mingw32-binutils-2.38/bin/i686-w64-mingw32-ld:
/nix/store/...-i686-w64-mingw32-stage-final-gcc-13.0.0-lib/i686-w64-mingw32/lib/libstdc++.dll.a:
error adding symbols: archive has no index; run ranlib to add one
We restore the index by running ranlib explicitly.
