tools: Simplify BITS_PER_LONG define
Do it using (__CHAR_BIT__ * __SIZEOF_LONG__), simpler, works everywhere,
reduces the complexity by ditching CONFIG_64BIT, that was being
synthesized from yet another set of defines, which proved fragile,
breaking the build on linux-next for no obvious reasons.
Committer Note:
Except on:
gcc version 4.1.2 20080704 (Red Hat 4.1.2-55)
Fallback to __WORDSIZE in that case...
