attached are strace outputs from Fedora and Debian. I can see one suspicious 
place in that - this is the first main difference between Fedora and Debian:

Fedora strace:
    open("m4", O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = 5
    fcntl(5, F_GETFD)                       = 0x1 (flags FD_CLOEXEC)
    fchdir(5)                               = 0
    getdents(5, /* 14 entries */, 32768)    = 456
    getdents(5, /* 0 entries */, 32768)     = 0
    close(5)                                = 0

Debian strace:
    open("m4", O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = 5
    fcntl(5, F_GETFD)                       = 0x1 (flags FD_CLOEXEC)
    fchdir(5)                               = 0
    getdents(5, /* 14 entries */, 32768)    = 456
    getdents(5, /* 0 entries */, 32768)     = 0
    close(5)                                = 0

In other words on Debian find does not change the working directory before 
calling lgetxattr syscall. That's why lgetxattr does not see the file and 
returns ENOENT (No such file or directory).

Does anybody here guess what's going on? (before I investigate it further)
