The testcase relies on us folding cabs() to pow/sqrt late (at link time)

/* We require a linker plugin because otherwise we'd need to link
   against libm which we are not sure here has cabs on all targets.
   This is because collect2 invokes ld on the -O0 object code
   which does not have folded cabs.  */

can you try if using __builtin_cabs instead of cabs works for you?
It might be solaris isnt a TARGET_C99_MATH target and thus cabs isn't
detected as builtin?
