groff has system headers overrides in its sourcecode which it
generates as fallbacks but in some cases when a system header includes
math.h via include <> directive it lands in the override header and
causes compile issues, seen with clang+libc++, this patch makes sure
that right defines are available before including it

+Subject: [PATCH] Include config.h
+
+This helps avoid the include conflicts where <stdlib.h> is including
+<math.h> and since -I./lib is used and a local math.h wrapper is
+residing in there, the build breaks since stdlib.h really wants the
+standard system math.h to be included, this ensures that right macros
+are predefined and included before stdlib.h is included
