respectively r1.9 and r1.6 of base gcc ones adding #define
NO_IMPLICIT_EXTERN_C. While here add the missing #define
NO_UNSAFE_BUILTINS to gfortran/gcc 4.2, Bump all REVISIONs.

clean it up.
More recent gcc have a cleaner fix, where fixincludes has been moved to
another directory that it truly owns, but in our case, we do not need to
clean up the fake directory as it's just been created.
okay pascal@, naddy@
is enabled on in base; except for gcc 3.3, which does not have PIE support and
therefore needs to pass -nopie to the linker.
Also, sync powerpc pthread specs with base. From Brad.
ok naddy@
same time, make sure that g++ is never installed alongside a higher version
of libstdc++, so that stuff will always link to the correct library.

libc.so from OpenBSD 5.0, and tweaks the ada scripts to LD_LIBRARY_PATH
the bundled library.
That way, we should be able to get away by providing a new bootstrap ways
less often (preferably every release, but things won't break if we do it
even LESS often).
(from OpenBSD 5.0-release), thanks ajacoutot@ for hosting the distfile.
- check that the bootstrap egcc can actually run; the reason for failure
due to missing libs is now clear (previously it was a cryptic "C compiler
cannot create executables" type message during configure).
builtins.c:
Allow MD backend to prevent the optimization of a bcopy() or memmove() of
size 1 (the size being known at compile-time) into an inline mempcpy()
expansion, which will in turn expand into a byte load and store operation.
This expansion loses precious address alignment information at some point
(because everybody knows that you can read a byte from any address, right?),
and this loses bigtime on strict alignment platforms which lack the ability
to accesse bytes directly, such as alpha (unless compiling with -mbwx and
runnning on a BWX-capable cpu).
config/alpha:
Require alignment of local arrays on word boundaries, and enable
the builtins.c `one-byte memcpy' workaround.
