updated patch for libgcc

Fixes an error about {mul,div}{d,x,t}c3 which wants to be built for different
modes / different types;

output is
/scratch/obj.i686/gcc-4.3/i686-linux-gnu/./libgfortran/.libs/libgfortr
an.so: undefined reference to `__divdc3'
/scratch/obj.i686/gcc-4.3/i686-linux-gnu/./libgfortran/.libs/libgfortran.so:

We need to compile for each of the dc, xc, tc variants separately, due to
implementation details (macros). lib2funcs_{d,x,t}c variables and corresponding
pbjects are used for this.
