* Removed startup code patches in lib/csu regarding kernel to userland
ABI.
* Aligned stack layout on NetBSD stack layout.
* Generate valid stack pointers instead of offsets by taking into account
_minix_kerninfo->kinfo->user_sp.
* Refactored stack generation, by moving part of execve in two
functions {minix_stack_params(), minix_stack_fill()} and using them
in execve(), rs and vm.
* Changed load offset of rtld (ld.so) to:
execi.args.stack_high - execi.args.stack_size - 0xa00000
which is 10MB below the main executable stack.

-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
