object splitting is not done under sparc solaris with gcc-4.2.2

I've used gcc-4.2.2 and ghc-6.8.1 to build ghc-6.8.2. For some reason object splitting is not done although for ghc-6.8.1 it worked fine.

-bash-3.00$ ll hello
-rwxr-xr-x   1 maeder   wimi     3907865 May 23 11:38 hello

-bash-3.00$ ghc --info
