Actually I think it should be the same version.  This is just like libffi.

One problem is AM_PROG_LIBTOOL, which is the part of libtool.
GCC autoconf doesn't use libtool since we have in-tree
libtool.  To use GCC autoconf, we need also use the rest of
libtool support in GCC source tree. That means it will make
libsanitizer depends on GCC source tree.

That's strange but on x86 I see 

CDPATH="${ZSH_VERSION+.}:" && cd ../../../libsanitizer && /bin/sh
/export/users/izamyati/tmp_gcc/missing --run aclocal-1.11 -I .. -I ../config
configure.ac:5: error: Please use exactly Autoconf 2.64 instead of 2.68.
../config/override.m4:12: _GCC_AUTOCONF_VERSION_CHECK is expanded from...
configure.ac:5: the top level
autom4te: m4 failed with exit status: 1
aclocal-1.11: autom4te failed with exit status: 1
make[2]: *** [../../../libsanitizer/aclocal.m4] Error 1

during build for following configuration

../configure --disable-bootstrap --enable-clocale=gnu --with-system-zlib
--enable-shared --with-demangler-in-ld --with-fpmath=sse
--enable-languages=c,c++,fortran 

My head is at r193515.

Did I miss anything?
