[libc] Potential wrong syscall number reference in linux_file.cpp

[gytsen]

While browsing the File implementation of the new LLVM libc, I spotted what I believe to be a potential typo in the linux file implementation:

The code looks for the SYS__llseek syscall number in the #if defined statement on line 78. However, when doing the actual syscall, __llvm_libc::syscall is called with SYS__lseek as argument on line 80. If I'm not mistaken that is a typo and the call should read

long ret = __llvm_libc::syscall(SYS__llseek, lf->get_fd(), offset >> 32,
                                  offset, &result, whence);

instead.

If this is not the case, feel free to close this issue as not relevant.
