According to my test that still results in the literal value of
"(64 - 8)".

Alright. But we should be able to special-case it with a two #if checks on
the __SIZEOF_LONG__ value and BUILD_BUG_ON() when __SIZEOF_LONG__ is not
of one of the ususal sizes.

And while we're at it, we might as well add a BUILD_BUG_ON check for
KSYM_NAME_LEN too, since we are also hard coding that field width, and
we'd like to be alerted if that value ever changes.
