Rollup merge of #140254 - bjorn3:rustc_panic_abort_abort, r=petrochenkov
Pass -Cpanic=abort for the panic_abort crate The panic_abort crate must be compiled with panic=abort, but cargo doesn't allow setting the panic strategy for a single crate the usual way using `panic="abort"`, but luckily per-package rustflags do allow this. Bootstrap previously handled this in its rustc wrapper, but for example the build systems of cg_clif and cg_gcc don't use the rustc wrapper, so they would either need to add one, patch the standard library or be unable to build a sysroot suitable for both panic=abort and panic=unwind (as is currently the case). Required for https://github.com/rust-lang/rustc_codegen_cranelift/issues/1567
