I don't believe the breakage (issues such as mixed real/complex arithmetic
wrongly converting the real operand to complex type, with implications for
NaNs and signed zeros) is of any relevance to the GDB tests.
I'd think the right approach is simply to see if the compiler accepts a
trivial source file of the form
_Complex float cf;
_Complex double cd;
_Complex long double cld;
and if it does, then presume complex support is present.
