glcpp: Handle bison-3.6 error message changes
In bison's commit 72c9fa4510eb (skeletons: use "end of file" instead of "$end") in bison-3.6, '$end' was changed to 'end of file' in error messages. Since our glcpp test cases contain the expected output text, they rely on the particular messages printed by bison. The test case 084-unbalanced-parentheses fails when Mesa is built with bison-3.6 due to this change. To allow the test to pass on all supported versions of bison, we: 1. Change '$end' -> 'end of file' in the .expected file, and 2. Normalize the error generated by the test case with the same replacement Cc: mesa-stable Closes: Reviewed-by: Pierre-Eric Pelloux-Prayer <> Part-of: <> (cherry picked from commit df29d0a111da3a555d8f0751722ca70fe0c5ffc0)
