New description:

 When using g95 as the fortran compiler, numpy won't build.  This is
 because the g95 fortran compiler doesn't set the linker_exe key of the
 executables dict.  Thus you get a KeyError:
 {{{

 customize UnixCCompiler
 customize UnixCCompiler using build_ext
 customize G95FCompiler

 }}}
 The current syntax in `fcompiler/__init__.py`, in `get_flags_linker_exe`
 does not protect against this error.  My guess is that `linker_exe` should
 simply be set properly in the g95 fcompiler class.
