Missing llvm-readelf command

[rruuaanng]

The latest LLVM release supports the llvm-readelf command, but it is not present in

rust/src/bootstrap/src/lib.rs

Lines 62 to 65 in ddd36bd

	const LLVM_TOOLS: &[&str] = &[
	"llvm-cov", // used to generate coverage report
	"llvm-nm", // used to inspect binaries; it shows symbol names, their sizes and visibility
	"llvm-objcopy", // used to transform ELFs into binary format which flashing tools consume

.

Please let me know if my suggestion has any issues, thanks!

llvm-readelf is an alias to llvm-readobj with just a slightly different cli. You should be able to use llvm-readobj: https://llvm.org/docs/CommandGuide/llvm-readobj.html#differences-to-llvm-readelf On Unix systems you can force it into readelf compat mode by setting arg0 to "readelf". I believe we can't use symlinks inside components, so we did have to duplicate the executable if we want. FWIW we don't include every tool LLVM provides, but just those that people said they actually need.

You're right. It seems that this doesn't require upstream support. Thanks!
