As noticed by Thomas, we call the UPPERCASE macro a lot, and it slows down
startup quite a bit.
Optimize it by implementing it in make, rather than forking a shell + tr.
The implementation is heavily based on the 'up' macro from gmsl
(http://gmsl.sf.net)
With this in place, startup time is ~5 times lower.

Since the documentation cleanup is done by the main Makefile in a
global way, there's no need to do that on a per-package basis in the
generic package infrastructure.

This new infrastructure allows to write simpler .mk files for packages
not using the autotools as their build system, by factorizing many
common steps (download, extract, patching), and will more easily allow
Buildroot-wide changes in how the packages are handled.
The main macro is called GENTARGETS and works similarly to the
AUTOTARGETS macro that already exists for autotools-based
packages. However, the set of variables to be defined before calling
the macro is different. Refer to the documentation for details.
