Subject: [PATCH] Make configure test for LD_NO_UNDEFINED_FLAG on Solaris work
 w/autoconf 2.69

After upgrading from autoconf 2.68 to 2.69, this test started failing with
"conftest.c", line 149: undefined symbol: NULL
so use a raw 0 pointer to avoid header dependencies in the autoconf
generated test case.
