Log message:
*: recursive bump for icu 78.1

Log message:
rust: Support flock() on illumos.

Required to bootstrap 1.91.0 which otherwise fails with try_from() not
supported.

Log message:
rust: work around panic when building as non-root

During the bootstrap it seems to copy everything under $PREFIX/lib to a
staging area for some reason. This is not ideal because it may lead to
circumvention buildlink3's intents. But more urgent is that it breaks
non-root builds if there are unreadable files (e.g. setuid binaries)
installed by other packages. Skip such files.

Thread 'main' panicked at src/bootstrap/src/lib.rs:1816:17:
