[Buildroot] [PATCH 4 of 5 v3 for 2014.08] manual-text: make sure URLs are displayed if a link text was provided

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

When the asciidoc source contain URLs of the form:
    http://example.com[An example website]
the text representation of the manual would only contain:
    An example website
without displaying the actual URL.

This patch adds an asciidoc configuration file that sets the inline macros
for several URL types so that the display becomes:
    An example website [http://example.com]
For URLs where no link text was provided, the display becomes:
    http://example.com
which is the same as before.

v3: no changes
v2:
- link to relevant documentation (which was hard to find)
- refine so that the display is identical to before when no link text is
  provided.
