Backport of #9976.

This fixes a bug in the creation of workspace arrays for a call
to lapack_lite.zgelsd, which led to segmentation faults when
a RHS was passed in that had larger size than the size of the
matrix.

There have been a lot of changes in linalg.py and this fix requires more work to pull out the relevant bits. I don't think this is worth pursuing for an end of the line minor release, so closing.
