[PATCH RFC 04/10] [UNTESTED] image: Add support for relocating crypto_algos in linker lists

[Alexandru Gagniuc]

Function pointers from crypto_algos array are relocated, when
NEEDS_MANUAL_RELOC is set. This relocation doesn't happen if the algo
is placed in a linker list. Implement this relocation.
