    xen: arm: drop LDFLAGS_DIRECT emulation specification.
    
    The current -maarch64elf fails when cross-building arm64 on Ubuntu Raring 
due
    to a missing file "ldscripts/aarch64elf.xr". This is undoubtedly an Ubuntu 
gcc
    bug, hwever when investigating I found that this option was not necessary at
    all since we provide an explicit linker script when linking the hypervisor
    (AFAICT all -m<foo> does is override the default linker script).
    
    LDFLAGS_DIRECT is also used when linking the intermediate built-in.o files 
but
    -m<emulatin> is not needed for this since it isn't linking the final image 
and
    we are calling the linker with the correct, cross if necessary, name.
    
    However it does appear to be potentially useful to supply -EL in both cases 
to
    ensure that we get little endian images. (I just happened to spot that Linux
    does this, for both arm and arm64, although I expect we are unlikely to trip
    over such toolchains these days).
    
    Tested with cross-builds of arm32 and arm64 as well as a native arm32 build.
