Major build system changes

Major build system changes

- Implemented ARMv7 userspace
- Shifted build system about to do so
 > `make all` processes user apps first
   This is so they are compiled for the initrd
 > Syscalls header changed to use #define instead of enum
   Allows ARMv7 assembly file to use it
- Moved most of my libgcc functions to ld-acess
 > ld-acess needed them, so remove code duplication

NOTE: Broke dependencies for nasm in user code
- I need to properly separate NASM and GAS objects, will
  do that in next commit.
