Michal Simek d58c007498 microblaze: Add support for run time relocation
Microblaze is using NEEDS_MANUAL_RELOC from the beginnging. This is causing
issues with function pointer arrays which need to be updated manually after
relocation. Building code with -fPIC and linking with -pic will remove this
limitation and there is no longer need to run manual update.

By default still old option is enabled but by disabling NEEDS_MANUAL_RELOC
code will be compiled for full relocation.

The patch does couple of things which are connected to each other.
- Define STATIC_RELA dependency to call relocate-rela to fill sections.
- REMAKE_ELF was already enabled but u-boot file can't be used because
  sections are empty. relocate-rela will fill them and output file is
  u-boot.elf which should be used.
- Add support for full relocation (u-boot.elf)
- Add support for early relocation when u-boot.bin is loaded to different
  address then CONFIG_SYS_TEXT_BASE
- Add rela.dyn and dynsym sections

Disabling NEEDS_MANUAL_RELOC U-Boot size increased by 10% of it's original
size (550kB to 608kB).
