Cross-compilation fixes:

- GCC >4.9:
Newer toolchains trigger more warnings, which by default are
treated as errors. Disable this while building the tools as this
will be a recurring problem in the future.

close #105

- FreeBSD: Fix some fetch.sh scripts which fails as FreeBSD's patch
fails to patch two .info files. We ignore this for the time being.

patch(1) problems workaround

. NUL input in 2 source files cause patch(1)
to truncate the input (and fail the patches); a sed
command removes the NULs
. in binutils/ld, configdoc.texi is patched to be removed
but some patch(1)es leave an empty file, causing build problems;
this file is explicitly removed.

Replace wget with ftp as default in fetch scripts

This default is overriden by curl when it is available on the system.

This allows for the fetch script to work on MINIX systems without any
additions from PKGSRC, while requiring either a netbsd compatible ftp or
curl to be installed on other systems.

Cross compile on minix support

* Remade patch so it works with minix patch tool.

* New MINIX tar support -ox, so revert back to it

In fetch scripts, tar had been replaced by bsdtar as the prebvious
tar did not support the -o flag under minix, which is required to
prevent usage of tar file stored user and group information.

This introduces portability problems. As our new tar tool now
support that flag revert back to improve portability.

Makefiles updates to imporve portability

Made sure to be consistent in the usage of braces/parenthesis at

Upgrading build system to new NetBSD revision

The tested targets are the followgin ones:
* tools
* distribution
* sets
* release

The remaining NetBSD targets have not been disabled nor tested
*at all*. Try them at your own risk, they may reboot the earth.

For all compliant Makefiles, objects and generated files are put in
MAKEOBJDIR, which means you can now keep objects between two branch
switching. Same for DESTDIR, please refer to build.sh options.

Regarding new or modifications of Makefiles a few things:
* Read share/mk/bsd.README
* If you add a subdirectory, add a Makefile in it, and have it called
by the parent through the SUBDIR variable.
* Do not add arbitrary inclusion which crosses to another branch of
the hierarchy; If you can't do without it, put a comment on why.
If possible, do not use inclusion at all.
* Use as much as possible the infrastructure, it is here to make
life easier, do not fight it.

Sets and package are now used to track files.
We have one set called "minix", composed of one package called "minix-sys"

Partially import gcc and binutils

They are used as build tools for cross compilation. This import does
not include the full distribution. Rather, it sports a shell script
that will download and patch the distribution when compiled from
/usr/src/tools (yet to be committed). This part of the source tree is
only necessary for cross compilation. It's not used or compiled for
native builds.
