OpenBLAS @0.2.20_1: libgcc* should be a runtime dependency

Port: OpenBLAS


gcc is used as Fortran compiler for OpenBLAS. The resulting library is linked against libgfortran and libquadmath which are provided by the corresponding libgcc port:

otool -L /opt/local/lib/libopenblas-r1.dylib
	/opt/local/lib/libopenblas-r1.dylib (compatibility version 0.0.0, current version 0.0.0)
	/opt/local/lib/libgcc/libgfortran.4.dylib (compatibility version 5.0.0, current version 5.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.0.0)
	/opt/local/lib/libgcc/libquadmath.0.dylib (compatibility version 1.0.0, current version 1.0.0)

port provides /opt/local/lib/libgcc/libgfortran.4.dylib
/opt/local/lib/libgcc/libgfortran.4.dylib is provided by: libgcc

port provides /opt/local/lib/libgcc/libquadmath.0.dylib
/opt/local/lib/libgcc/libquadmath.0.dylib is provided by: libgcc

The corresponding libgcc version should therefore be added as a runtime dependency.

I noticed this myself when doing a "port uninstall leaves" which uninstalled gcc6 and libgcc6 and left OpenBLAS broken. (The output shown above is now from the +gcc7 variant of OpenBLAS).
