Updates libc from 0.2.186 to 0.2.188

Release notes

Sourced from libc's releases.

0.2.188

Changed

• Restore Send and Sync for DIR (35b062263401)

These were removed in 0.2.187 because libc does not actually make Send and Sync guarantees about DIR (or other extern types), but this caused some crates to break. The traits are added back for now to allow time to migrate, but will be removed again in the future; please make sure your crates are not relying on libc::DIR: Send or libc::DIR: Sync.

0.2.187

This release contains a number of improvements related to 64-bit time_t configuration. Of note the existing RUST_LIBC_UNSTABLE_* environment variables have been replaced with configuration options. The new way to use these is:

RUSTFLAGS='--cfg=libc_unstable_musl_v1_2_3' cargo ...
RUSTFLAGS='--cfg=libc_unstable_gnu_time_bits="64"' cargo ...

Being able to set this via RUSTFLAGS makes it easier to only apply configuration to specific targets (and notably, not the host if build scripts are used).

There are two other notable changes:

• The 32-bit windows-gnu targets now respect libc_unstable_gnu_time_bits

• uClibc now supports a similar configuration option:

  RUSTFLAGS='--cfg=libc_unstable_uclibc_time64'

As a reminder, these options are under active development and may change in the future (hence the "unstable" in the name). It likely that we will harmonize everything under a single configuration option before considering them stable.

Support

• Add support for aarch64-unknown-linux-pauthtest (#5065)
• Add support for new QNX targets (#5241)
• Better document breaking change policy and recommended usage (#5179)

Added

• Android: Add POSIX_SPAWN_* constants (#5104)
• Android: Add getpwent, setpwent, and endpwent (#5160)
• Android: Add preadv2 and pwritev2 (#5157)
• Android: Add seccomp_notif* structures (#5224)
• Android: Add timer_[create, delete, getoverrun, gettime, settime] (#5108)
