So i think there is something wrong with the gcc7 build via pkgsrc on sparc64.

The libgfortran.so has undefined symbols of the cab* functions.
There are patches for gcc7 that have the focus to adjust these issues
for NetBSD, but something is not working out for gfortran on sparc64:

bash-5.0# more patch-gcc_config.gcc
$NetBSD: patch-gcc_config.gcc,v 1.4 2018/11/09 11:22:13 mrg Exp $

Workaround netbsd's compatibility non-C99 cabs (causes gfortran link failures)

bash-5.0# cat patch-gcc_config_netbsd-protos.h
[...]
+#ifndef _NETBSD_PROTOS_H_
+#define _NETBSD_PROTOS_H_
+
+double __c99_cabs (double complex);
+float __c99_cabsf (float complex);
+long double __c99_cabsl (long double complex);
[...]

Should i start a new mailing since this seems not to be a problem of
math/blas or math/coinmp?
