  For example, to disable compiler optimizations and inlining,
  you can use the following the gcflags.

  $ go build -gcflags="-N -I"

The flag to disable inlining appears to be incorrect.

It should be `-l` and not `-I`, such that it reads:

  $ go build -gcflags="-N -l"

Whoops, fixed the typo. Thanks!
