ccfb965433 Add META_MODE support. 
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

165557e269 With rotating kernel dumps the higest dump number is not necessarily the 
last one. To make it easier to find the last one create symlinks with 'last'
suffix that will point to the files of the last coredump, eg.:

	info.last -> info.5
	textdump.tar.last.gz -> textdump.tar.5.gz

349d039bdb - When checking if a dump exists on the given device there is no need to 
provide dump directory. Eliminate this redundant argument. This changes
  the usage, but the only risk here is that a warning will be printed
  about directory given as device.

- Update usage of -C option.

- When clearing dump header from the given device there is also no need to
  provide dump directory, although additional arguments for -c were not
  documented.

- Document that -v can be used with -c and that list of devices can be given.

df0b82f150 Compare kernel dump header magic with textdump magic using strncmp() 
rather than the memcmp() which is used for regular dumps: the
textdump string is one character shorter, so we need to stop
comparing at the end of the string.

Use independent version checking logic for architecture-specific
version number vs. textdump version number, as the version sequences
may (someday) differ.

d32e7ba722 Don't consider being unable to open the bounds file worthy of printing 
at LOG_WARNING by default; instead, consider it something to be printed
to the tty when 'verbose' mode is set.  This avoids printing out extra
lines at every boot on a system with crash dumps enabled, but that has
not yet had to generate a crashdump.
