make clean-target fails at x86_64-unknown-linux-gnu/32/libjava

[Manuel López-Ibáñez]

make clean-target fails at x86_64-unknown-linux-gnu/32/libjava when
doing target 'mostlyclean-local' because it tries to execute:

find . -name '*.lo' -print | xargs /bin/sh ./libtool rm -f

and we get:

libtool: error: you must specify a MODE.

when it should execute:

find . -name '*.lo' -print | xargs /bin/sh ./libtool --mode=clean rm -f

I don't have any idea of autotools but it would be nice to provide a
fix. How can I fix this?

Cheers,

Manuel.
