Fixes #82730.

Explanations

The INVALID_DOC_ATTRIBUTES lint was marked as "will become a hard error into the future" for quite some time so making it deny by default.

Waiting on rust-lang/backtrace-rs#524 for now.

  (rust-lang/rust#121956)
netbsd-srcmastr pushed a commit to NetBSD/pkgsrc that referenced this pull request Oct 13, 2024
This is based on the pkgsrc-wip rust180 package, retaining
the main pkgsrc changes as best as I could.

Pkgsrc changes:
 * Adapt checksums and patches.
 * Make this work again on big-endian aarch64 (at least on NetBSD).
 * Make the choice of GCC = 12 work for sparc64 by testing options
   after options.mk is included (which is required...).  Makes this
   work on NetBSD/sparc64 10.0 again.
