autoconf: don't try to build Emacs files

When building autoconf for the target, we already passed EMACS="no" to
prevent autoconf from building Emacs mode files. But we weren't doing
that when building autoconf for the host. This causes problems when
'emacs' is not really emacs, but a sort of clone like Jove. So we also
pass EMACS="no" when building host-autoconf to avoid autoconf
./configure script from detecting emacs and then use it to build .elc
files from .el source code.

xcb-util: add dependency on libxcb

The xcb-util lacks a dependency on libxcb. Without this dependency, it
fails to build with:

checking for XCB... no
configure: error: in `/home/thomas/projets/buildroot/output/build/xcb-util-0.3.9':
configure: error: The pkg-config script could not be found or is too old.  Make sure it
is in your PATH or set the PKG_CONFIG environment variable to the full
path to pkg-config.

Alternatively, you may set the environment variables XCB_CFLAGS
and XCB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

pcre: always enable the 8-bits version

Commit 7154798a461a8b2c (pcre: add support for 16 bits and 32 bits
variants), added in preparation to the introduction of the Qt5
packages, could break other packages that use pcre.

Even though by default the pcre 8 bits library is selected if no other
variant is selected, a randpackageconfig, or an user, could
potentially enable the 16 bits variant even if a package requires the
8 bits variant.

This has caused a number of build breakage on packages like ngrep,
cegui, nmap and others in the autobuilders.

In older to solve this, we simply unconditionally build the 8-bits
variant. Since each variant is only ~90k in size, it's probably not
worth the effort giving the possibility of building the 16 bits
variant only.

libglib2: don't build tests

Add a patch that provides an additional --disable-tests option to the

Disabling the build of tests has two benefits:
 * Prevents the build of a lot of code that doesn't build on noMMU
   platforms.
 * Reduces the build time.

libglib2: use system pcre when available

By default, glib builds its own internal copy of the pcre library, but

possibility when pcre is already selected in the Buildroot

Bump to latest 2.22.2 version and revamp available options.

* Remove the assumed enable/disable defaults since these seem to change

* Switch from build "X" menu options to just X, add some help and sort.

* Introduce new option to install binaries (or not) to reduce bloat for

jpeg: convert to a real package

jpeg is a virtual package, but since it is listed in the dependencies
of other packages, it should obey to all the normal make rules for
packages. Notably, the jpeg-show-depends target is mandatory for the
graph-depends script to work.

Instead to implement such a make target manually, make jpeg a normal
generic-package, except that it doesn't have any source.
