Update configure.ac to make it build on OpenBSD

This update is to make libsecp256k1 build on OpenBSD (more specifically OpenBSD 5.7 with Autotools 2.69).

Without the "AM_PROG_CC_C_O" line in configure.ac, ./autogen.sh crashes with "Makefile.am: C objects in subdir but `AM_PROG_CC_C_O' not in `configure.ac'\nautoreconf-2.69: automake failed with exit status: 1".
