No need to have the HAVE_ARCH_BUG.* / HAVE_ARCH_WARN.* defines, when
the generic implementation can just use #ifndef on the macros themselves.
Also, introduce __WARN() in the generic case, so the generic WARN_ON()
can use arch-specific code for when the condition is true.
Built on powerpc, i386, sh and sparc64.
