Unfortunately we need to have autotools check for sendmmsg() [1]
to fix failure on old distros
/usr/src/ltp/testcases/kernel/syscalls/sendmmsg/sendmmsg01.c   -lltp -o sendmmsg01
/usr/src/ltp/testcases/kernel/syscalls/sendmmsg/sendmmsg01.c: In function 'sender_thread':
/usr/src/ltp/testcases/kernel/syscalls/sendmmsg/sendmmsg01.c:53: warning: implicit declaration of function 'sendmmsg'
/tmp/ccqXXRS6.o: In function `sender_thread':
/usr/src/ltp/testcases/kernel/syscalls/sendmmsg/sendmmsg01.c:53: undefined reference to `sendmmsg'
