[PATCH][Revised] Pass -no_pie on SYSTEMSPEC for darwin11

[Jack Howarth]

  The gcj compiler needs to pass -no_pie for linkage on darwin11 due to the new 
-pie
default of the linker. The attached patch accomplishes this by passing -no_pie 
on SYSTEMSPEC
for *-*-darwin[12]*. Since Darwin10 supports -no_pie in its linker, I included 
it in the
triplet match to simplify the syntax. Bootstrap and tested on 
x86_64-apple-darwin11.
Okay for gcc trunk with PR added to comment as requested?
               Jack
ps This change also works for gcc-4_6-branch in concert with a backport of
r175089 and r175108.
