So, maybe not a gfortran problem.
% gfcx -o z -fdump-tree-original a.f90
% grep csqrt a.f90.004t.original
sq = __builtin_csqrtf (z);
% nm z | grep sqrt
U csqrtf@@FBSD_1.1
'sq = csqrt(z)' is compiled to 'sq = __builtin_csqrtf (z);' and
__builtin_csqrtf() is mapped to your math library's csqrtf()
function. If your math library does not have csqrtf(), then
there is a fall back function in libgfortran. Looking at the
fallback function shows a design flaw. Don't know if that you're
problem.
