When you build gcc/gfortran you must configure --with-quad= set to the same 
place where you set --prefix= when you configured and installed libquad. This 
allows the configury to find libquad when building libgfortran.

I did not see where you used --with-quad when you configured gcc.  At least it 
does not show from the -v output.
