Support for LINUX Boot
To enable/disable feature, PcdLinuxBootEnable can be used
1.	Follow directions on http://osresearch.net/Building/ to compile the heads kernel and initrd for qemu-system_x86_64
2.	Copy the following built files
(1) initrd.cpio.xz  to LinuxBootPkg/LinuxBinaries/initrd.cpio.xz
(2) bzimage to LinuxBootPkg/LinuxBinaries/linux.efi
