Subject: [PATCH] chore(deps): Bump libc from 0.2.186 to 0.2.188 (#567)

Bumps [libc](https://github.com/rust-lang/libc) from 0.2.186 to 0.2.188.

<blockquote>
<h2>0.2.188</h2>
<h3>Changed</h3>
<ul>
<li>Restore <code>Send</code> and <code>Sync</code> for <code>DIR</code>
(<a
href="https://github.com/rust-lang/libc/commit/35b062263401733cd89065c6a553640f2ba51ff1">35b062263401</a>)</li>
</ul>
<p>These were removed in 0.2.187 because <code>libc</code> does not
actually make <code>Send</code> and <code>Sync</code>
guarantees about <code>DIR</code> (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
<code>libc::DIR: Send</code> or
<code>libc::DIR: Sync</code>.</p>
<h2>0.2.187</h2>
<p>This release contains a number of improvements related to 64-bit
<code>time_t</code> configuration.
Of note the existing <code>RUST_LIBC_UNSTABLE_*</code> environment
variables have been replaced
with configuration options. The new way to use these is:</p>
<pre lang="sh"><code>RUSTFLAGS='--cfg=libc_unstable_musl_v1_2_3' cargo
...
RUSTFLAGS='--cfg=libc_unstable_gnu_time_bits=&quot;64&quot;' cargo ...
</code></pre>
<p>Being able to set this via <code>RUSTFLAGS</code> makes it easier to
only apply configuration to
specific targets (and notably, not the host if build scripts are
used).</p>
<p>There are two other notable changes:</p>
<ul>
<li>
<p>The 32-bit <code>windows-gnu</code> targets now respect
<code>libc_unstable_gnu_time_bits</code></p>
</li>
<li>
<p>uClibc now supports a similar configuration option:</p>
<pre lang="sh"><code>RUSTFLAGS='--cfg=libc_unstable_uclibc_time64'
</code></pre>
</li>
</ul>
<p>As a reminder, these options are under active development and may
change in the future
(hence the &quot;unstable&quot; in the name). It likely that we will
harmonize everything under a
single configuration option before considering them stable.</p>

<li>Add support for new QNX targets (<a
href="https://redirect.github.com/rust-lang/libc/pull/5241">#5241</a>)</li>
<li>Better document breaking change policy and recommended usage (<a
href="https://redirect.github.com/rust-lang/libc/pull/5179">#5179</a>)</li>
</ul>
