Comment (by fbissey):
OK, so I have done my inspection:
1) list of linbox dependency that we want to be there: ntl, fplll, flint,
mpfr, iml. Those are direct build dependencies

flint is not in the current list. m4ri and m4rie can be removed as they
are looked for by `configure` but not used.
2) we want to have opencl (`--without-ocl`) to be turned off, at least
for binary build.
3) because `sage/libs/linbox/linbox.pyx` has been given a block
{{{
# distutils: extra_compile_args = LINBOX_CFLAGS
# distutils: libraries = LINBOX_LIBRARIES
# distutils: library_dirs = LINBOX_LIBDIR
}}}
the entry in `modules_list.py` doesn't need `libraries = linbox_libs`.
`cblas_include_dirs` can stay as its content is somehow not included in
`fflas-ffpack.pc` (but it is in `fflas-ffpack-config --cflags`). Similarly
`fflas-ffpack.pc` has no information on the blas/lapack libraries - may be
it should - you would inherit the correct stuff without having to add
anything. Someone check this on a vanilla install please.
4) Do we want lapack support in `fflas-ffpack`? That would mean changing
`LINBOX_BLAS="$(pkg-config --libs cblas)"` to `LINBOX_BLAS="$(pkg-config
--libs lapack cblas)"` this has an impact on the previous item as you
really need to know which libraries are used (especially if your linker is
dumb). Note: you may want at least `LINBOX_BLAS="$(pkg-config --cflags
--libs cblas)"` in case the headers are in a funny location.
