building rust 1.60.0 on SPARC with 1.59.0 fails w/ lint error

[nbriggs]

It's probably really an upstream problem, but could be solved by patching the rust distribution (removing a test case) so that it doesn't fail and abort the build when testing the lint-docs component due to inline assembly not being supported on SPARC archictectures:

Building stage0 tool lint-docs (sparcv9-sun-solaris)
    Finished release [optimized] target(s) in 1.55s
warning: the code example in lint `named_asm_labels` in /scratch/clone/components/rust/rustc/rustc-1.60.0-src/compiler/rustc_lint/src/builtin.rs failed to generate the expected output: did not find lint `named_asm_labels` in output of example, got:

  |         ^^^^^^^^^^^^^^^^


error: aborting due to previous error


Rustbook (sparcv9-sun-solaris) - rustc

The easy workaround is to build with -i make option and ignore the failure.
