arch/SConscript:
aout_machdep.h and ecoff_machdep.h are no longer bridging headers, since support of these formats is limitted to alpha.
base/loader/exec_aout.h:
Include the alpha specific version of aout_machdep.h, since only the alpha version of aout will be supported for now.
base/loader/exec_ecoff.h:
Include the alpha specific version of ecoff_machdep.h, since only the alpha version of ecoff will be supported for now.
