LTTng-modules, starting from v2.8, has a mechanism to be built directly
into a Linux kernel image, that is, not as loadable kernel modules. For
this the `CONFIG_LTTNG_CLOCK_PLUGIN_TEST` and `CONFIG_LTTNG` Make
variables were introduced. They need to be explicitly set to `m` here to
build the project as loadable kernel modules.

lttng-modules' Makefile already uses the Linux buildsystem to build its
modules, so just switch to using the new kernel-module infra.
To be noted: lttng-modules' Makefile uses $(shell pwd) that expects the
PWD to be the Linux' top build directory, which is not the case for us.
However, it uses to detect a conflict between a stale static version.h
and a generated version.h (due to the switch to uapi). This is of no
consequence to us, because we can't have a Linux build directory with
such stale files.

The Buildroot coding style defines one space around make assignments and
does not align the assignment symbols.
This patch does a bulk fix of offending packages. The package
infrastructures (or more in general assignments to calculated variable
names, like $(2)_FOO) are not touched.
Alignment of line continuation characters (\) is kept as-is.
The sed command used to do this replacement is:
find * -name "*.mk" | xargs sed -i \
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#'
Brief explanation of this command:
^\([A-Z0-9a-z_]\+\) a regular variable at the beginning of the line
\([?:+]\?=\) any assignment character =, :=, ?=, +=
\([^\\]\+\) any string not containing a line continuation
\([^\\ \t]\+\s*\\\) string, optional whitespace, followed by a
line continuation character
\(\s*\\\) optional whitespace, followed by a line
continuation character
Hence, the first subexpression handles empty assignments, the second
handles regular assignments, the third handles regular assignments with
line continuation, and the fourth empty assignments with line
continuation.
This expression was tested on following test text: (initial tab not
included)
FOO = spaces before
FOO = spaces before and after
FOO = tab before
FOO = tab and spaces before
FOO = tab after
FOO = tab and spaces after
FOO = spaces and tab after
FOO = \
FOO = bar \
FOO = bar space \
FOO = \
GENIMAGE_DEPENDENCIES = host-pkgconf libconfuse
FOO += spaces before
FOO ?= spaces before and after
FOO :=
FOO =
FOO =
FOO =
FOO =
$(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C
AT91BOOTSTRAP3_DEFCONFIG = \
AXEL_DISABLE_I18N=--i18n=0
After this bulk change, following manual fixups were done:
- fix line continuation alignment in cegui06 and spice (the sed
expression leaves the number of whitespace between the value and line
continuation character intact, but the whitespace before that could have
changed, causing misalignment.
- qt5base was reverted, as this package uses extensive alignment which
actually makes the code more readable.
Finally, the end result was manually reviewed.

Since the trailing slash is stripped from $($(PKG)_SITE) by pkg-generic.mk:
$(call DOWNLOAD,$($(PKG)_SITE:/=)/$($(PKG)_SOURCE))
so it is redundant.
This patch removes it from $(PKG)_SITE variable for BR consistency.

This commit bumps the various LTTng components to their latest stable
version: 0.7.7 for liburcu, 1.1.1 for babeltrace, 2.1.3 for libust and
2.1.2 for lttng-modules.
For babeltrace, the patch
lttng-babeltrace-02-fix-build-old-compilers.patch has been removed
because it has been merged upstream as of version 1.1.1. This is also
the reason why the package no longer needs to be autoreconfigured.

When using lttng-tools for userland tracing with lttng-libust lttng-modules
is not required, thus a dependency on building lttng-modules and a kernel is
overkill for lttng-tools. It also hides it from a user not wanting to build
a kernel. A comment has been added to lttng-modules to show a user that
lttng-modules is dependent on a kernel build.
