Failure on armel architecture

[SnarkBoojum]

I tried to compile elpi 1.18.2 on the armel architecture, and it failed with:

------------------------------------------------------------------
Log of the first failure: _log/elpi+trace-browser-cut.log
------------------------------------------------------------------
executable: /home/jpuydt/elpi-1.18.2/_build/install/default/bin/elpi

Compilation time: 0.009
------------------------------------------------------------------
End log of the first failure: _log/elpi+trace-browser-cut.log

where I don't see an error message... how can I get more insight on the issue?
