Subject[PATCH] selftests: filesystems/epoll: fix build error
Date
epoll build fails to find pthread lib. Fix Makefile to use LDLIBS
instead of LDFLAGS. LDLIBS is the right flag to use here with -l
option when invoking ld.

gcc -I../../../../../usr/include/ -lpthread epoll_wakeup_test.c -o .../tools/testing/selftests/filesystems/epoll/epoll_wakeup_test
/usr/bin/ld: /tmp/ccaZvJUl.o: in function `kill_timeout':
epoll_wakeup_test.c:(.text+0x4dd): undefined reference to `pthread_kill'
/usr/bin/ld: epoll_wakeup_test.c:(.text+0x4f2): undefined reference to `pthread_kill'
/usr/bin/ld: /tmp/ccaZvJUl.o: in function `epoll9':
epoll_wakeup_test.c:(.text+0x6382): undefined reference to `pthread_create'
/usr/bin/ld: epoll_wakeup_test.c:(.text+0x64d2): undefined reference to `pthread_create'
/usr/bin/ld: epoll_wakeup_test.c:(.text+0x6626): undefined reference to `pthread_join'
/usr/bin/ld: epoll_wakeup_test.c:(.text+0x684c): undefined reference to `pthread_tryjoin_np'
/usr/bin/ld: epoll_wakeup_test.c:(.text+0x6864): undefined reference to `pthread_kill'
/usr/bin/ld: epoll_wakeup_test.c:(.text+0x6878): undefined reference to `pthread_join'
