tst_qobject: fix the detection for GCC

Q_CC_GNU is defined on compilers that masquerade as GCC (Clang, ICC),
so using it to work around GCC-specific bugs is wrong. Introduce a
local define for _only_ GCC and use it in place of Q_CC_GNU.

Drive by: version-fence a test we now know it's been fixed upstream,
and correct the link to the corresponding bug report.
