[Bonmin] how to build a completely static version version of bonmin

[Jeff Linderoth]

Hi Andreas,

I just wanted to respond to the list to say "thank you", and also to say
that the combination of 

1) export AM_LDFLAGS='-all-static' 
and
2) ADD_FFLAGS='-static'

were able to get an all-static bonmin built for me.

Thanks again.

Cheers,
-Jeff
