I have applied, with the following changes:

    [Thomas:
     - add runtime test
     - drop dependency on OpenBLAS, which is not needed in a minimal
       configuration

Could you please:

 (1) Review the runtime test, to see if it can be improved with some
     better testing.

 (2) Review the OpenBLAS dependency, to see if it needs to be added as
     an optional dependency in some way.

This part is a bit annoying, as it's duplicated from python-numpy.mk. I
looked a bit, but couldn't really find a good way of avoiding this
duplication.

Thanks!

Hello,
thank you Thomas for merging this serie and also for adding the runtime
test, I did try to provide it but could not get it to work.
I will give it a try in the next few days

  Don't hesitate to post even a non-working version that people can comment on. 
Please do post it as an RFC though (--subject-prefix=RFC). And of course there's 
no promise that people will *actually* comment on it :-).

Could you give some details on what didn't work? Our runtime test
infrastructure is (I believe?) reasonably simple and straightforward to
use, with tons of existing examples.

The one thing that was tricky here is that most Python test cases use a
CPIO filesystem loaded as an initrd, but that doesn't work for SciPy as
the filesystem is too large for an initrd. Which is why my test case
uses an ext2 filesystem on a hard drive.

Hello Thomas

I was trying to get the runtime test (the emulator) to execute the scipy
fulltest ("python -c import scipy; scipy.test()"), as I was thinking it
would be the best thing to do.
But it's not a straightforward scenario and it's super heavy, you need the
repo sources and the pytest suite.

Running small but several portions of the lib is probably the best thing to
do.

Indeed, full test suites are often too heavy/too complex to run in the
context of our runtime tests, so we tend to create smaller test cases
instead.

Of course, my very small test case could certainly be improved with
additional tests, if necessary.

Best regards,

Thomas
