[PATCH v2 16/17] Sparc: relax gas testsuite whitespace expectations

[Jan Beulich]

In a subsequent change the scrubber is going to be changed to retain
further whitespace. Test case expectations generally would better not
depend on the specific whitespace treatment by the scrubber, unless of
course a test is specifically about it. Adjust relevant test cases to
permit blanks where those will subsequently appear.
---
This is adding just the blank that is going to be needed; imo it would
generally be better if test case expectations were, from the very
beginning, written to focus on what is being tested, rather than taking
verbatim copies of the respective tool's output.
---
v2: New.
