cross building fibers from i686-linux to i586-pc-gnu fails

[<janneke@gnu.org>]

Hi,

Running

    ./pre-inst-env guix build --target=i586-pc-gnu --system=i686-linux guile-fibers

(also using latest fibers f92e5cb4f78e7e3d3537bfc9622bc59ea99fe9a7) fails

while cross building from x86_64-linux works fine.  In the build
environment, ldd says:

and adding the location of ld.so.1 to LD_LIBRARY_PATH gives yet another error
