The ARM parasite head uses a pad of 228 bytes
to make the offset of the symbol __export_parasite_stack
representable in the ARM instruction set. This value
needs to be changed every time the value of the macro
PARASITE_STACK_SIZE changes.
This patch makes this manual interference redundant.

Sometimes we don't know the exact amount of data we would want
to send to parasite via args area (e.g. -- while draining fds).
Fix this, by moving the args area behind the parasite blob and
mmap-ing it with the run-time calculated size.

CFLAGS can be overriden, we need own flags here.

This facrots out common core members freeing into pstree.c
helper. Per-arch freeing helpers are now symmetrical to the
allocating ones.
This is a merge of two Cyrill's patches.

In case if here is a fast cpu and make is done in parallel
we may have the following error
| GEN arch/x86/sys-exec-tbl.c
| GEN arch/x86/syscalls.S
| CC arch/x86/crtools.o
| CC arch/x86/cpu.o
| CC arch/x86/syscalls.o
| LINK arch/x86/syscalls.built-in.o

| cc1: all warnings being treated as errors
| make[1]: *** [arch/x86/crtools.o] Error 1
| make: *** [arch/x86] Error 2
This is because crtools.c includes syscall.h but this header
is generated by a special script. So use $(deps-after) feature
provided by our make engine making sure the header is generated
before the deps are started to build.

The FPU data is quite CPU-type oriented,
thus move it to asm/fpu.h.

No need to walk up the directories if we need
to include protobuf file. This was always a bad
use of ability to walk the filesystem from other
headers.
Same time we don't need -I$(SRC_DIR)/protobuf/
in general makefile anymore.

It's been reported that we do not test if the tracee is 32bit
task running kn 64bit kernel. This patch adds such test.
