Actually recent autoconf versions can support this - an example for
linux/netlink.h can be found, e.g., at
http://svn.python.org/projects/python/branches/release26-maint/configure.in

# On Linux, netlink.h requires asm/types.h
AC_CHECK_HEADERS(linux/netlink.h,,,[
#ifdef HAVE_ASM_TYPES_H
#include <asm/types.h>
#endif
#ifdef HAVE_SYS_SOCKET_H
#include <sys/socket.h>
#endif
])

(AC_CHECK_HEADERS(asm/types.h sys/socket.h) must be called before)
