Log message:
rust: Upgrade to version 1.75.0.

Pkgsrc changes:
 * Adjust patches and cargo checksums to new versions.
 * For an external LLVM, set dependency of llvm >= 16, in accordance
   with the upstream changes.
 * Mark that on NetBSD we now need >= 9.0, so 8.x is no longer supported.
 * On NetBSD/sparc64 10.x, we now need GCC 12 to build the embedded
   LLVM, which is version 17; apparently GCC 10.4 or 10.5 mis-compiles it,
   resulting in an illegal instruction fault during the build.

Log message:
rust: avoid .old files in the final package

Log message:
rust: Update illumos pkgsrc bootstrap libraries.

Log message:
rust: use system libunwind

Log message:
lang/rust: remove references to build-time DESTDIR

When the package is installed, the temporary DESTDIR directory doesn't
exist anymore, so there's no point referring to it.

Bump PKGREVISION.

Log message:
rust: add a CHECK_PORTABILITY_SKIP

Log message:
rust: update to version 1.74.1.

Pkgsrc changes:

 * Remove NetBSD-8 support (embedded LLVm requires newer C++
   than what is in -8; it's conceivable that this could still
   build with an external LLVM)
 * undo powerpc 9.0 file naming tweak, since we no longer support -8.
 * Remove patch to LLVM for powerpc now included by upstream.
 * Minor adjustments, checksum changes etc.
