First draft with newlib integration
Forgot to fix elf2flt path

C++ sould work fine now, but elf2flt doesn't.
Basic libstdc++ support without exceptions
Disable exceptions in libstdc++
Too many changes to summarize

-Rewrote MakeSyscalls
-Got rid of old_os.h finally
-Tore apart ndless installer and resources
-Removed some deprecated stuff
-Fixed miscellaneous warnings and errors
Fixed linking of newlib stubs by grouping libc and libsyscalls together
Fixed some subtle bugs
Fix .init_array and .fini_array relocation in elf2flt
Bugfix for lseek, file IO in newlib-c++
Some more syscalls

Remove stubs.cpp
Use GCC 4.9 and -fPIC instead of "-pie", fix compile error in libndls
