While the autotools infrastructure was using FOO_MAKE_OPT, generic packages
were typically using FOO_MAKE_OPTS. This inconsistency becomes a problem
when a new infrastructure is introduced that wants to make use of
FOO_MAKE_OPT(S), and can live alongside either generic-package or
autotools-package. The new infrastructure will have to choose between either
OPT or OPTS, and thus rule out transparent usage by respectively generic
packages or generic packages. An example of such an infrastructure is
kconfig-package, which provides kconfig-related make targets.
The OPTS variant is more logical, as there are typically multiple options.
This patch renames all occurrences of FOO_MAKE_OPT in FOO_MAKE_OPTS.

The structure of the buildroot manual is not always clear. There is a large
number of chapters, and some chapters seem to overlap. The distinction
between general usage and developer information is not always clear.
This patch restructures the manual into four large parts:
- getting started
- user guide
- developer guide
- appendix
Except for the names of these parts, the section names are not yet changed.
Content-wise there are no changes yet either. This will be handled in
subsequent patches.
In order to achieve the introduction of a new level 'parts' above
'chapters', the section indicators (=, ==, ===, ...) of several sections
have to be moved one level down. Additionally, the leveloffset indication to
asciidoc has to be removed. Finally, to maintain more or less the same level
of detail in the table of contents, the toc.section.depth attribute is

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.

As reported in bug #7172 [0], setting BR2_TARGET_LDFLAGS to a value
containing a $ sign can lead to unexpected results.
This is because it is very hard to know when the $ sign gets evaluated:
- in the Buildroot-level make
- in the shell called by the Buildroot-level make
- in the package's own build-system, either at configure time, in the
Makefile, in a shell in the Makefile...
So, it is very difficult to know how much escaping that would need.
A proposal is to use a shell variable to pass such values unmolested.
But it is not that simple either, since it still contains a $ sign, and
there is not much certainty as to when it would be evaluated.
Instead, just document this limitation, both in the help text for
BR2_TARGET_LDFLAGS, and in the known-issues section in the manual.
Does not really fix#7172, but at least the limitation is documented.
