[Bug libfortran/17748] New: libgfortran contains undefined references to _environ

[peter at pogma dot com]

libgfortran references environ which is not available to shared libraries directly on 
darwin. This means 
that we can not build fortran shared libraries without undefined symbols.

The solution is to use crt_externs.h and #define environ (*_NSGetEnviron()) in 
libgfortran/runtime/
environ.c.
