    libx11: fix build error
    
    libx11 build fails with this error:
    
    fatal error: bits/long-double-64.h: No such file or directory
    | compilation terminated.
    
    This is due to the fact that "makekeys" should be compiled for the host
    since it is executed at build time to generate ks_tables.h. Since we have
    the X11 include files in the standard path of oe-core, we can remove the
    X11_CFLAGS from Makefile.
    
    (From OE-Core rev: c2bc26a163be231f489ea13e6f7226715765732e)
