 Ok, replacing `LD_LIBRARY_PATH` with `LIBRARY_PATH` in my patch above (and
 setting that to a path along which `libgcc*` can be found) also works.

 But I also noticed other things (when doing `./sage -f ...`):
 {{{

 }}}
 (Haven't tracked that further down, but it's strange, provided
 `$SAGE_LOCAL/[lib/]` '''is''' used there, since both libraries are
 present.)

 Also, `spkg-install` (I think) shouldn't delete previous versions until
 the build succeeded.
