build: Use common rules to build the packages

To simplify the packages Makefile, and remove some code duplication,
use a generic rule to build the package. The default rule run the
typical configure, make, make install sequence with default arguments.
The packages are free to extend the arguments, redefine the command
used, etc.

build: Blacklist x86_64 for build-all

The x86_64 target is broken for a long time and since it makes
trouble if building toolchains with the build-all script,
it should be avioded to build it there.
It was requested to add a blacklist to the build-all script
and not to remove the target itself.

build: Include defs.mk when building the common libraries

The definitions from defs.mk are always needed, so it make no sense to
only include them when a TARGET is given.
