[Bug middle-end/19551] [3.4/4.0 Regression] LAPACK routine claic1.f bug

-fno-builtin only matters in not adding pure attribute to csqrtf.
If you start the #5 testcase with
_Complex float csqrtf(_Complex float) __attribute__((pure));
instead, it fails even with -fno-builtin.
Reproduced on i386-redhat-linux, looking into it.
