Severity: grave

Justification: renders package unusable
Dear Maintainer,
The qtbase-opensource-src build is currently broken on sparc. While
investigating the bug describing this breakage, #773590, I found that
the actual code generated by gcc-4.9 is fine but the linker is
incorrectly arranging sting literal function arguments resulting in
garbage values being passed to functions.
The result is that moc doesn't produce any output files and doesn't
print correct diagnostic messages.
It appears to be specifically the gold linker that the ./configure
script selects by default that has the problem. If the bfd linker is
selected instead the build completes normally and the packages
generated work in my testing.
I'm working on a minimal testcase to report the gold bug but until
this is fixed it can be worked around by disabling gold on sparc at
configure time.
This patch is one way this could be done, it fixes the build on my
sparc system.
