[dev-qt/qtcore:4] Explicitly list all codecs in QT4_TARGET_DIRECTORIES.

As a side effect, qmake is run inside each of the codecs dirs,
fixing a "pre-stripped files" regression introduced in commit
52bcb4af3258474d1be5bd6c24c1126d2b915b86.

[qt4-build-multilib.eclass] Always run qmake in the build tree root.
[dev-qt/qttranslations:4] Remove redundant definition of src_compile().

[dev-qt/qthelp:4] Fix docs generation.
[qt4-build-multilib.eclass] Respect also AR, OBJCOPY, and STRIP.
[qt4-build-multilib.eclass] Stop exporting pkg_setup.
[qt4-build-multilib.eclass] Get rid of QT4_EXTRACT_DIRECTORIES.

When doing out-of-source builds, syncqt needs to be run. The problem
is that it insists on running on all Qt modules, even those that
have not been extracted, therefore it's bound to fail.

Since we're going to need out-of-source builds for multilib support
(we could use multilib_copy_sources but it'd nullify the benefits
of partial extraction), just remove the whole QT4_EXTRACT_DIRECTORIES
machinery now.

It was very difficult to maintain a precise list anyway...
[qt4-build-multilib.eclass] syncqt is automatically run by configure when needed.
[qt4-build-multilib.eclass] Initial multilib support.
