I was reminded recently about a comment I made back in February 2017
about getting guix support for x32, aka x86_64-linux-gnux32, aka
x86_64-linux but with 32-bit data structures.  The idea was that by
using 32-bit pointers there'd be a not insignificant speed-up of code
execution¹.  I am uncertain how true this is, or which packages would
really benefit from this.

Interestingly,
%glibc-cross-x86_64-linux-gnux32-2.35/lib/ld-linux-x32.so.2 --help
suggests that it still benefits from our --tune parameters, which is not
the case for i686-linux's ld-linux.so.2.
