the $$ solution is not very efficient as the commands
are executed by the shell all the times.

What about using :

LAPACK_LIBS := $(shell mkoctfile -p LAPACK_LIBS)
BLAS_LIBS := $(shell mkoctfile -p BLAS_LIBS)
FLIBS := $(shell mkoctfile -p FLIBS)

this should be a more traditional solution already used
in the octave Makefile
