This commit adds the variable LDLIBS_TOOLCHAIN that, by default,
add the gcc static library to the link command.
This variable can be overriden as an environmental variable or as a make
parameter to allow the use of different toolchains different from gcc.

This commit changes the way libc is built.
Instead of building a hierarchy of objects linked into the
microkernel, libc minimal is built as a static library and
linked against the microkernel binary.
The location of the libc is configurable with the variable
KLIBC_DIR. This gives the flexibility to build against a
different libc other than minimal.

This commit includes the genIdt tool as part of the kconfig
basic tools. Now the genIdt tool is built automatically as
part of the whole kernel project.

In some cases you might want to compile sources in a
customer location, for example share code for samples
that runs in nano and micro kernels.
Set SOURCE_DIR in the project Makefile to achieve this.

This commit removes several CFLAGS inherited from Linux Kconfig
that are not used in the current build system.
- The option fno-delete-null-pointer-checks is not used.
- O2 is not a default option and the symbol
CONFIG_CC_OPTIMIZE_FOR_SIZE is not supported.
- The option allow-store-data-races=0 is not used.
- The fno-stack-protector was being added twice and is not
a default parameter.

This commit adds support for the qemu target.
This target will generate the kernel binary and will
launch a qemu instance running the binary.
Currently, only the x86 generic pc and the arm tilm3s6965
BSPs are supported with emulation.

This commit substitutes references to the linux string in variable
names.
It changes the LINUX prefix and uses the TIMO prefix (short for
tiny mountain)
It changes the vmlinux prefix for tinymountain prefix.
It preserves linux references found in licenses, comments giving
credits and from scripts that are not supported by the current build
system yet, like rpm generation.

This commit fixes the target clean functionality.
Originally, the clean and mrproper targets search for the
Documentation and samples directories and their respective
Makefiles.
Our current directory structure is not including Documentation
directory yet. Also, there is not support for a global Makefiles
at samples directory.
This commit deletes references to Documentation directories for
clean and mrproper targets as well.
Also, This commit deletes the reference to sample directory for
clean target.
Finally, this commit temporary fixes the references to assembly
files .s extensions. This has been marked as a BUG until all .s
files can be renamed to .S files.
