PIE code can't use glibc helpers so instead of passing
CR_NOGLIBC macro in every source file pie code uses just
pass it in pie/Makefile.

PIE code use own handmade stack so we need -fno-stack-protector
option to eliminate compilation warning if -fstack-protector
passed in command line CFLAGS.

In case if CFLAGS is overriden from command line we don't
see our headers anymore. So provide mandatory options in
ccflags-y variable to fix that.

Because we need util-net.c for both PIE code and
a regular code, just move it to pie/ directory
and build with -fpie option, this way we can reuse
compiled file in main program without additional
compilation pass.

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.

Otherwise pie may not be re-built if headers

* The linker script pie/pie.lds.S is generated from the template
pie/pie.lds.S.in by prepending the output architecture specification.
The output architecture is defined by the variable LDARCH.
* Blobs are generated by objcopy instead of ld because the ARM linker
fails to produce a binary when supplied a script.

This patch simplifies pie build. Main change is replaces explicit rules by
implicit which reduces Makefile size and makes it more readable.
Notes:
1) intermediate build files are preserved.
2) Both blobs are linked with util-net.o. Restorer blob doesn't require it,
but this allows to avoid explicit rule for it.
v3:
1) Fixed parasite build.
2) Fixed blobs deps - %.bin and %.bin.o can now be build in parallel.
3) Updated restorer link: restorer is not linked with util-net.o anymore.
