[PATCH] [Microblaze]: PIC Data Text Relative

Hi Andrew --
Please take a look at the test case description:
https://gcc.gnu.org/wiki/HowToPrepareATestcase
and see if you can do one of the following:
- Modify the regex expression in the scan-assembler to accept
either format of generated output
or
- Add { dg-option } directives to turn off your new options
if specified. (You should be able to specify -mno-pic....)
or
- Duplicate the test cases and add { dg-option } directives
to specify the correct options, with and without your
new options.
or
- Add test cases with a { dg-option } directive with your
new options.
This is not required -- your patch appears to work OK. Normally,
the new PIC Data options would not be used when running the test
suite, so the tests would not fail. It's just nice to have the
test suite updated when new options are added.
