Since 810ba387bec3c5b, some form of these options are enable
by default. Specifically:

- Kept FORTIFY level 2 option as the default is now level 1.
- Removed all SSP options as the default now uses the best
  option based on toolchain support.
- Similar to SSP, for RELRO, the default now uses the best
  option based on toolchain support.
- Completely drop PIC PIE as it defaults =y
