This patch reverts back the changes to HOSTCFLAGS and HOSTLDFLAGS When we were building complete binaries to get constants (such as ptrace register layout on stack) from host userspace headers, we needed to make the arch for building HOST binaries match our one: i.e. on a 64bit system compiling 32bit binaries, we compile 32-bit hostprogs and need, say, 32-bit ncurses. Now we can revert that - that avoids problem with, say, menuconfig and ncurses, on a system which can't compile well 32-bit programs.
