0cdf705cc6 Enable optional GCC install and GCC improvements
-By adding MKGCC=yes and MKGCCCMDS=yes on the make commandline
   it is now possible to compile and install GCC on the system.

   Before doing this, if you are not using the build.sh script,
   you will need to call the fetch scripts in order to retrieve
   the sources of GCC and its dependencies.

 -Reduce difference with NetBSD share/mk

   Move Minix-specific parameters from bsd.gcc.mk to bsd.own.mk,
   which is anyway patched, so that bsd.gcc.mk is now aligned
   on the NetBSD version.

 -Clean libraries dependencies, compiles stdc++ only if gcc is
   also compiled (it is part of the gcc sources)

 -Correct minix.h header sequence, cleanup spec headers.

 -Fix cross-compilation from a 32bit host targeting MINIX/arm

c566d4623b Allow install of binutils and import texinfo
- Enable installing binutils from the base system.

 - Import texinfo which is required for the binutils tools
   to be compiled.

 - Also adapted the fetch rules to correctly generate the
   gitignore files for gcc, and allow the case of multiple
   modules in the same directory, as found in gnu/dist.

Warning: This patch has an entry in docs/UPDATING

5a0585359d ARM divsi3.S: raise(SIGFPE) when called for
. raise(SIGFPE) for modulo-0/divide-0 operations in
	  internal int division functions
	. gcc: do not link with -lgcc anywhere so these internal
	  functions are always used from libc instead of (sometimes)
	  masked by -lgcc
	. together fixes test53 on ARM

b1c4ba4ab6 ARM updates
Due to the ABI we are using we have to use the earm architecture
moniker for the build system to behave correctly. This involves
then some headers to move around.

There is also a few related Makefile updates as well as minor
source code corrections.

b8a678ef1d 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   In fetch scripts, tar had been replaced by bsdtar as the prebvious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.

d19d7d58aa Toolchain upgrade and portability improvements.
upgrade to NetBSD CVS release from 2012/10/17 12:00:00 UTC

Makefiles updates to imporve portability

Made sure to be consistent in the usage of braces/parenthesis at
least on a per file basis. For variables, it is recommended to
continue to use braces.

9152e1c5a7 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"

18a5822eff 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.
