ubuntu should work fine with ./buildAll

fedora required a bit of help (see history here).

Also a small progress with ARM miner, investigation led me to the part of code,
I already marked with "?" long time ago when trying to understand some old miner ...

having

    uint32* powHashU32 = (uint32*)powHash;

    for(uint32 i=0; i<256; i++)
    {
        mpz_mul_2exp(z_target, z_target, 1);
        if( (powHashU32[i/32]>>(i))&1 )
            z_target->_mp_d[0]++;
    }

It needs ">>(i%32))" I'd say - and I do not know why it works fine on x64, but the change helped to get seemingly proper targets on ARM.
Still no share submitted, so I do not know if it helped.
