Note that <code>go install</code> placed the <code>stringutil.a</code> object
in a directory inside <code>pkg/linux_amd64</code> that mirrors its source
directory.
This is so that future invocations of the <code>go</code> tool can find the
package object and avoid recompiling the package unnecessarily.
The <code>linux_amd64</code> part is there to aid in cross-compilation,
and will reflect the operating system and architecture of your system.

Go command executables are statically linked; the package objects need not
be present to run Go programs.
