Bump libgtk3 to 3.11.5.

The relevant patches are updated or discarded.
Add a package that installs DejaVu fonts

Some sort of fonts is required to properly render the glyphs in GTK applications.
DejaVu fonts are a start, but these can be changed later, if necessary.
systemd: fix build with uClibc toolchains

Currently, the build of systemd is broken with the internal toolchain
backend, because we have uClibc patches that add support for
execvpe(), but we also have a patch for systemd that adds execvpe(),
which was added when the internal uClibc didn't support execvpe().

However, simply dropping the patch is not a solution, as it would
break the build of systemd with any other uClibc than the ones built
with Buildroot. For example, a Crosstool-NG uClibc toolchain would
fail.

Beyond this execvpe() problem, there are also other problems that
prevented systemd from being built with unpatched uClibc.

This patch does the following:

 * Add sequence numbers of systemd patches.
 * Regenerate them to avoid fuzz.
 * Improve the uClibc compatibility patch so that it:
   - Detects whether execvpe() is available or not, and if not
     available provide an implementation.
   - Detects if dup3() is available or not, and if not available
     provide an implementation.
   - Detects if MSG_CMSG_CLOEXEC is defined or not, and if not, define
     it to the appropriate value.

This has been tested with uClibc internal toolchain, uClibc external
toolchain built with Buildroot, uClibc external toolchain built with
Crosstool-NG, and glibc external toolchain.

Fixes bug #6776.

busybox: copy config file from configure iso extract step

The three typical packages that use .config files in buildroot copy the
config file at different times in the build process:

    busybox copies its .config from the post-extract hook.
    linux copies its .config in the configure_cmds.
    uclibc copies its .config from the post-patch hook.

Copying the .config file from the configure step is the only way to properly
support an OVERRIDE_SRCDIR that does not yet have the .config file, because
the extract and patch steps are skipped in that case.

For example, when setting a BUSYBOX_OVERRIDE_SRCDIR to a cleanly extracted
busybox tarball:

$ make busybox-dirclean busybox
rm -Rf [..]/output/build/busybox-custom
>>> busybox custom Syncing from source dir
>>> /home/tdescham/repo/contrib/busybox-1.21.1
rsync -au --exclude .svn --exclude .git --exclude .hg --exclude .bzr
            --exclude CVS /home/tdescham/repo/contrib/busybox-1.21.1/
            [..]/output/build/busybox-custom
>>> busybox custom Configuring
/bin/sed -i -e "/\\<CONFIG_NOMMU\\>/d"
                            [..]/output/build/busybox-custom/.config
/bin/sed: can't read [..]/output/build/busybox-custom/.config:
                                            No such file or directory
make: *** [[..]/output/build/busybox-custom/.stamp_configured] Error 2

This patch modifies busybox.mk to copy the config file from the configure
step instead, as linux is doing, and fixing the described scenario.

jimtcl: don't attempt to handle ccache internally

jimtcl tries to use 'ccache' (a non-buildroot host version) which may not
exist on the host system. If ccache is enabled in buildroot, the compiler
used by jimtcl is:
ccache <buildroot>/.../ccache <buildroot>/.../<tuple>-gcc

If ccache is not present on the host, this results in the build error:

ccache <buildroot>/.../ccache <buildroot>/.../<tuple>-gcc
-D_GNU_SOURCE -Wall  -I. -fpic -pipe -Os    -c -o jim-subcmd.o jim-subcmd.c
make[1]: ccache: Command not found

This patch passes 'CCACHE=none' to the 'configure' script, disabling the
internal handling of ccache, so that ccache can be transparently passed
through CC.
