Use `asm-generic/error.h` instead of `error.h` to fix error:\r\n> /usr/include/linux/errno.h:1:10: fatal error: 'asm/errno.h' file not found\r\n\r\n2. Initial global vals to fix errors, eg:\r\n> libbpf: invalid relo for 'filter_ports_len' in special section 0xfff2; forgot to initialize global var?..\r\n> Error: failed to open BPF object file: 0\r\n> Makefile:66: recipe for target '.output/tcpconnect.skel.h' failed\r\n\r\n3. Ignore `EINTR` error info, eg: after `Ctrl-C` I got\r\n> Error polling perf buffer: -4\r\n\r\nSigned-off-by: Wenbo Zhang <ethercflow@gmail.com>ghprbCommentBodynullghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title=" libbpf-tools: fix tcpconnect compile errors" href="https://github.com/iovisor/bcc/pull/3026">PR #3026</a>: libbpf-tools: fix tcpconne...#62513472537460664bcc-pr #625625false6254994SUCCESS1596158850459https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/625/git625https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=fc25/625/625https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=fc26/625/625https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=fc27/625/625https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=fc28/625/625https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=ubuntu1604/625/625https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=ubuntu1710/625/625https://buildbot.iovisor.org/jenkins/user/yonghong-song/my-views/view/all/job/bcc-pr/label=ubuntu1804/625/
