This just looks like libffi isn't being linked to guile at all.  Can you 
verify that libffi was actually built and installed in the right place?  
Next, I would see what "CCLD guile" is really doing.  I'm not sure how 
guile is built these days, but maybe you just have to add V=1 to the 
"make" command line.

Indeed.  Libffi certainly builds on mipsel machines, as does Guile, so I
suspect this is an error configuring Guile.  Perhaps you needed to set
PKG_CONFIG_PATH, ɺɺ?

Can you please run "make V=1" so that we can see the complete command
used in the failing link (CCLD guile) command?  As Anthony Green said,
it appears that libffi was not linked.

I can think of a few possible reasons:

* Did you forget to run "ldconfig" after installing libffi?
* Was libffi present when you last ran Guile's configure?
* Is there a problem with pkg-config on your system?
  (What is the output of "pkg-config --libs libffi"?)

    Thanks,
      Mark
