Rollup merge of #127934 - Kobzol:checktools-better-error, r=onur-ozkan

Improve error when a compiler/library build fails in `checktools.sh`

Suggested by ``@RalfJung`` [here](https://github.com/rust-lang/rust/issues/127869#issuecomment-2235829643).

`x86_64-gnu-tools` should take ~45 minutes, let's see if this doesn't regress it.
