instead of using symlink. The symlink broke scons's built-in include dependency tacking. Interestingly once it was fixed scons discovered two circular dependency problems which are also fixed now. SConscript: Make targetarch directory in build tree and copy arch/alpha files to it instead of using symlink. The symlink broke scons's built-in include dependency tacking. arch/alpha/ev5.hh: Get rid of circular #include dependence. kern/kernel_stats.cc: Add needed header file. kern/linux/linux_syscalls.hh: kern/tru64/tru64_syscalls.hh: Replace targetarch/syscalls.hh with single template class declaration. --HG-- extra : convert_revision : b8551623c1d441c6eb8d0651387e97e373128814
