Adjust gcc.dg/lto/20120723_0.c for SPARC

[Eric Botcazou]

As noted by Martin in http://gcc.gnu.org/ml/gcc-patches/2012-08/msg00116.html, 
the testcase is invalid C and cannot pass on SPARC 32-bit because of the ABI.

Tested on SPARC/Solaris 10, applied on the mainline.

        * gcc.dg/lto/20120723_0.c: Skip on SPARC 32-bit.
