Comment(by leif):
I finally found out what we have to do to make GSL use ATLAS's CBLAS in
Sage: '''Nothing! 8D'''
(A closer look at {{{$SAGE_ROOT/devel/sage-main/module_list.py}}} helped.
I hope other ''Sage packages'' that require CBLAS will also link with
{{{libcblas.*}}}, not {{{libgslcblas.*}}}.)
The only thing we could (but perhaps shouldn't) do is run GSL's testsuite
with ATLAS's CBLAS library instead.
But since GSL's implementation is used as a fall-back in Sage, we should
leave it as is, and - if at all - only do an ''additional'' run of the
testsuite with ATLAS's CBLAS library. (But I've not yet figured out how
simple that is; in worst case we'd have to {{{make clean}}}, {{{make}}}
again with {{{LDFLAGS="$LDFLAGS -L$SAGE_LOCAL/lib -lcblas -latlas"}}} and
then {{{make check}}}.)
