Fix leul_to_cpu on big endian hosts

Commit 213acd2e introduced leul_to_cpu with a special code path for big endian
hosts. Unfortunately that code used preprocessor magic that didn't work.

This patch replaces the explicit ##s by glue() which is proven to work reliably,
enabling me to compile qemu on ppc again.
