So qemu doesn't like what it's been passed.  Unpacking what you posted:

qemu-i386 \
  -r 3.2.0 \
  -E LD_LIBRARY_PATH=WORKDIR/rootfs/usr/lib:WORKDIR/rootfs/lib \
  -L WORKDIR/rootfs \
  -E \
  WORKDIR/rootfs/usr/libexec/fc-cache \
    --sysroot=WORKDIR/rootfs \
    --system-only

For some reason an extra -E is being passed. Have you changed the
intercepts? This is what the script should look like:

  $ cat scripts/postinst-intercepts/update_font_cache
  #!/bin/sh
  set -e
  PSEUDO_UNLOAD=1 ${binprefix}qemuwrapper -L $D -E
${fontconfigcacheenv} $D${libexecdir}/${binprefix}fc-cache --sysro
ot=$D --system-only ${fontconfigcacheparams}

Note there's only one -E entry.
