alpha: Use absolute_pointer to define COMMAND_LINE

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

alpha:allmodconfig fails to build with the following error
when using gcc 11.x.

arch/alpha/kernel/setup.c: In function 'setup_arch':
arch/alpha/kernel/setup.c:493:13: error:
'strcmp' reading 1 or more bytes from a region of size 0

Avoid the problem by declaring COMMAND_LINE as absolute_pointer().
