Strangely, I found lsame in libmkl_lapack.a (which I guess is the Lapack
part of MKL).  I did a real ugly hack: I inserted the link flags to this
library in RHOME/src/modules/lapack/Makefile, where lapack.so is built.
That seems to have solved the problem.  The resulting build passes make
check w/o any error.

I think I'll just follow the advise in that README file, at least for now...

Thanks very much for your help!
