The former code used `target.contains("64")` to detect Elf64 targets,
but this is inaccurate in a few cases:
- `s390x-unknown-linux-gnu` is 64-bit
- `sparcv9-sun-solaris` is 64-bit
- `x86_64-unknown-linux-gnux32` is 32-bit
Instead the build script can use `CARGO_CFG_TARGET_POINTER_WIDTH` to
reliably detect 64-bit targets.

An excellent and much better idea, thanks! |

to reliably detect 64-bit targets for libbacktrace.
Also update to backtrace-sys 0.1.24 for rust-lang/backtrace-rs#122.
