isfinite needs _GNU_SOURCE defined on EL-5

Description

isfinite needs _GNU_SOURCE to be defined before including math.h on EL-5 or you'll get linker errors when linking liblwgeom. Adding the following to the top of g_box.c will fix the problem: 

#ifndef _GNU_SOURCE
#define _GNU_SOURCE
#endif

It seems the version of gcc on EL-5 is old enough that isfinite won't be included by default unless _GNU_SOURCE is defined, as the isfinite macro is a C99 feature.
