 I'm guessing gcc7 is missing the patch to make netbsd/arm use DWARF. It
 should be available on the latest GCC source code (and probably gcc10).
 Need to backport it.

 /usr/local/gcc7/lib/gcc/armv7--netbsdelf-eabihf/7.5.0/../../../libgfortran.so:
 warning: warning: reference to compatibility cabsf()

 This is another bug relating to gcc.

 I expect GFORTRAN_VERSION=10 (and removing some libtool packages) will
 work as a temporary workaround until gcc7 is patched.
