x86, bootup: add built-in kernel command line for x86 (v2)
Allow x86 to support a built-in kernel command line. The built-in command line can override the one provided by the boot loader, for those cases where the boot loader is broken or it is difficult to change the command line in the the boot loader. H.

This version changes absolutely nothing if CONFIG_CMDLINE_BOOL is not set (the default). Also, no space is appended even when CONFIG_CMDLINE_BOOL is set, but the builtin string is empty. This is less sloppy all the way around, IMHO. Note that I use the same option names as on other arches for this feature.
