The Intel C Compiler defines the macro __x86_64__. It does not define __amd64__  or __amd64. This leads to a build failure as /usr/include/xorg/servermd.h does not check for __x84_64__.

servermd.h use to check for __x86_64__ and the check was removed in this commit.

    Check for __amd64__, not __x86_64__.
    
    Spiritual revert of 1fa4de80fcfc697b5e5879cc351fb3e9dbf6acbe.  Intel's C
    compiler claims to be gcc-compatible; if they're not defining the same
    macros as gcc then that's their bug, not ours.  Even if we were to do
    this aliasing we should do it once and for all in servermd.h.
