It worked. 
It worked. I simply moved make distclean before ./configure and it worked!
I finally got it working! Thanks from the bottom of my heart.

This is more about debugging your build script then the branch itself.
Apparently you are running the configure two times and the second is not
selecting the natve compiler option.

I think you should remove the 'make distclean' from the script or
execute it before configuring.

This should be removing what as been produced by the first configure
invocation where you ask for the native compiler.
