I think this commit was fixed by:

commit a13ea3b30b02580c0f582f2c2435818aa1921a3d

    lsof: don't use host toolchain to determine target libc
    
    The lsof Configure script builds a test program using the host toolchain to
    test whether glibc is used. This test is broken in cross compilation
    environment. Set LINUX_CLIB to avoid the test. This should give the correct
    result even for non glibc toolchains, since all libc variants we support have
    the netinet/tcp.h header.
    
    Fixes:

At least, using a configuration similar to the one you pointed as failing
(http://autobuild.buildroot.org/results/ade/ade3629f72bf2195bde086a8c403197c0d1fdba3/),
I am not able to reproduce the problem.

I've therefore marked the patch as Rejected. If you still have the
issue, do not hesitate to get back to us.

Thanks a lot!
