package/thrift: add dependency on host-autoconf-archive

The ax_cxx_compile_stdcxx_11 macro bundled in thrift package is
brocken [1] and out of date.

Add autoconf-archive as dependency to use an updated version of this macro.

Since Thrift actually doesn't use that particular C++11 feature, add a
patch to make C++11 support optional.
