The libeina library uses the madvise() system call, that isn't
available on non-MMU systems. Also, several other components of EFL
use fork(). Therefore, the easiest solution is to simply disallow the
EFL as a whole on non-MMU systems.

Evas has an optional mechanism to do asynchronous preloading of
images. This mechanism is optional, and in commit
b6d92bf415 ("libevas: async image
preload support needs threads support in toolchain"), Peter made sure
to disable the asychronous preloading when no thread support was
available.
Unfortunately, it seems like disabling the asynchronous loading is
rarely used, and it in facts fails to build: a member of structure is
not present when asynchronous preloading is disabled, but the code
continues to use it.
Since the fix is not obvious, and all this mechanism seems to have
changed completely in EFL 1.8.x, and we probably don't care much about
EFL without threads, this commit adds a dependency of libevas on
thread support. Consequently, it also reverts commit
b6d92bf415 which is no longer necessary.
Of course, this commit propagates this additional dependency to the
reverse dependencies of libevas.

This patch removes deprecated symbol BR2_HAVE_DOCUMENTATION and all its
usage. Additionally, it removes the now unused BR2_DEPRECATED_SINCE_2012_11.

When a package A depends on config option B and toolchain option C, then
the comment that is given when C is not fulfilled should also depend on B.
For example:
config BR2_PACKAGE_A
depends on BR2_B
depends on BR2_LARGEFILE
depends on BR2_WCHAR
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
This comment should actually be:
comment "A needs a toolchain w/ largefile, wchar"
depends on BR2_B
depends on !BR2_LARGEFILE || !BR2_WCHAR
or if possible (typically when B is a package config option declared in that
same Config.in file):
if BR2_B
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
[other config options depending on B]
endif
Otherwise, the comment would be visible even though the other dependencies
are not met.
This patch adds such missing dependencies, and changes existing such
dependencies from
depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC
to
depends on BR2_BASE_DEP
depends on !BR2_TOOLCHAIN_USES_GLIBC
so that (positive) base dependencies are separate from the (negative)
toolchain dependencies. This strategy makes it easier to write such comments
(because one can simply copy the base dependency from the actual package
config option), but also avoids complex and long boolean expressions.

This commit adds a dependency of the libglib2 package on thread
support in the toolchain, since upstream libglib2 doesn't build
without thread support. The commit is rather large as it involves
propagating the dependency on thread support to all reverse
dependencies of the libglib2 package.
[Thomas: squash all patches into one, make a few minor fixes, the most
important one being to not add comments about MMU requirement when a
package doesn't work on !MMU platforms.]

The efl libraries depends on BR2_PACKAGE_EFL, so ensure enlightenment
selects it as well, otherwise kconfig complains.
