…iven `Mark`" This reverts commit b15785b.
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 `std` build script can use `CARGO_CFG_TARGET_POINTER_WIDTH`
to reliably detect 64-bit targets for libbacktrace.
Also update to backtrace-sys 0.1.24 for rust-lang/backtrace-rs#122.
If we detect a local rebuild (e.g. bootstrap compiler is the same version as target compiler), we set stage to 1. When trying to build e.g. UnstableBook, we use Mode::ToolBootstrap and stage is 1. Just allow Mode::ToolBootstrap and stagge != 0 if we are in a local_rebuild Signed-off-by: Marc-Antoine Perennou <Marc-Antoine@Perennou.com>
