Thanks for the suggestions which I received off-list.

I think I've sorted out the problem. Turns out it is crucial to set 
MAKE=gmake when running ./configure. This makes sure that gmake will be 
used in the subdirs:

$ MAKE=gmake ./configure [options]
$ gmake

I guess this is what I did back then without ever adding it to the 
documentation.

regards,
Markus
