While BR2_EXTERNAL_<NAME>_PATH was already documented, it was not
made obvious that it could be reused in post-biuld, post-image and
in-fakeroot scripts.
The BR2_EXTERNAL_<NAME>_DESC variable was not documented at all.
Update the manual to fix this.
Note: a2x chokes on this:
.Note:
Both +BR2_EXTERNAL_$(NAME)_PATH+ and +BR2_EXTERNAL_$(NAME)_DESC+ are
available [...]
and spits out a totally useless error message:
a2x: ERROR: "xsltproc" --stringparam toc.section.depth 1 --stringparam
callout.graphics 0 --stringparam navig.graphics 0 --stringparam
admon.textlabel 1 --stringparam admon.graphic 0 --stringparam
chunk.section.depth 0 --output "/home/ymorin/dev/buildroot/O/docs/manual/manual.html"
"/etc/asciidoc/docbook-xsl/xhtml.xsl"
"/home/ymorin/dev/buildroot/O/docs/manual/manual.xml" returned
non-zero exit status 6
So, we had to resort to using different quoting styles for each
variables. They are not semantically equivalent, but the rendering
is the same with the default CSS (which we are using). That's gonna
be good-enough for now...
