While tracking one bug report related to wrong package dependencies I've
noticed, that a bunch of the crypto modules are actually not
architecture specific, but either board/subtarget (x86/64) or board
(mpc85xx) specific.
So lets fix it, by making those modules architecture specific:
x86/64 -> x86_64
mpc85xx -> powerpc
