[PATCH,AIX] rs6000 output_aligned_decl_common fix

GCC toplev.c uses ASM_OUTPUT_ALIGNED_DECL_COMMON with a NULL decl to
emit the LTO marker, so the rs6000 implementation needs to test for
that situation.  config/darwin.c tests similarly.  With this patch,
gcc -flto produces correct output on AIX.

Bootstrapped on powerpc-ibm-aix7.2.0.0

Thanks, David
