[Buildroot] [PATCH 2 of 5 v4 for 2014.08] gendoc infra: use $(pkgname) instead of explicitly passing 'manual'

[Yann E. MORIN]

THomas, All,

On 2014-08-15 15:40 +0200, Thomas De Schampheleire spake thusly:
> In the gendoc infrastructure, using an assignment of the form
>     FOO = docs/$(1)/bar
> inside GENDOC_INNER does not work as expected: the $(1) value is empty here
> and the value of FOO becomes 'docs//bar'.
> 
> Parameters $(2), $(3), etc. do not have this problem. The specific thing
> about $(1) is that it is a parameter to GENDOC itself (indicating the
> document to create) and passed transparently to GENDOC_INNER.
> 
> This is different from the package infrastructures, where $(1) is set from
> $(pkgname). In fact, the same strategy could be used by the gendoc
> infrastructure as well, as $(pkgname) resolves to 'manual' for file
> docs/manual/manual.mk. This has the advantage that the described problem
> does not occur.
> 
> Note that this means that if we want to use the same GENDOC infrastructure
> for another document, it will have to reside in a separate directory than
> the manual.

Tested by building the manual with and without a .config.
