<p> <!-- CL 31141 -->
The Go tool now remembers the value of the <code>CGO_ENABLED</code> environment
variable set during <code>make.bash</code> and applies it to all future compilations
by default to fix issue <a href="https://golang.org/issue/12808">#12808</a>.
When doing native compilation, it is rarely necessary to explicitly set
the <code>CGO_ENABLED</code> environment variable as <code>make.bash</code>
will detect the correct setting automatically. The main reason to explicitly
set the <code>CGO_ENABLED</code> environment variable is when your environment
supports cgo, but you explicitly do not want cgo support, in which case, set
<code>CGO_ENABLED=0</code> during <code>make.bash</code> or <code>all.bash</code>.

<p> <!-- CL 29991 -->
The environment variable <code>PKG_CONFIG</code> may now be used to
set the program to run to handle <code>#cgo</code> <code>pkg-config</code>
