The BITS variable conveniently allows to simplify the assignment for
UTS_MACHINE.

Hello,

I found that while working on a riscv extension that (probably) will
require to add another suffix to UTS_MACHINE. For now this patch only
saves a line, but conditionally appending another string this is very
convenient. But also without this motivation, I consider this a nice
little cleanup.

Best regards
Uwe
