Faidon Liambotis 50a54f4edc Build compiler-rt for wasm32 and wasm64
Current shortcomings/future work:

 * Unfortunately this currently takes the form of a separate, standalone
   build (with the just-built stage2 toolchain), which makes this a
   little more convoluted. The upstream compiler-rt build system does
   not have a way (that I could find) to manually add additional targets
   to the build.

 * GNU strip (binutils) does not understand the WebAssembly binary, so
   dh_strip fails. llvm-strip does, but a) does not understand all the
   arguments that dh_strip passes (e.g. -N), b) fails with "invalid
   relocation offset" on --strip-debug (but works with --strip-all).

   This currently passes -X to dh_strip to exclude them from being
   stripped entirely. Invoking llvm-strip manually with --strip-all can
   be considered in the future.

* The wasm32/wasm64 binaries are, by design, architecture-independent.
  With this commit, they are being built in every architecture, and
  shipped in the libclang-common-X.Y-dev package, which is arch: any,
  but ships both architecture-dependent (native/host compiler-rt) and
  architecture-independent files (include headers etc.).

  In a future iteration, the wasm32/wasm64 compiler-rt library could be
  factored out to a separate (arch: all) package. This is left
  outstanding because it should probably happen alongside a different
  split for libclang-common-X.Y-dev that will include splitting the
  native libclang-rt as well.
