Add a new "none" platform that only builds utilities
This makes it possible to build generally-useful utilities such as grub-mount even if the rest of GRUB has not been ported to the target CPU. * configure.ac: Add "none" platform. Default to it for unsupported CPUs rather than stopping with a fatal error. Don't downgrade x86_64-none to i386. Define COND_real_platform Automake conditional if the platform is anything other than "none". Don't do any include directory linking for "none". * Makefile.am: Skip building grub-core and all bootcheck targets if !COND_real_platform. * include/grub/time.h: Don't include <grub/cpu/time.h> if GRUB_UTIL is defined.

* configure.ac: Add "none" platform. Default to it for unsupported
|
||||
CPUs rather than stopping with a fatal error. Don't downgrade
|
||||
x86_64-none to i386. Define COND_real_platform Automake conditional

if the platform is anything other than "none". Don't do any include

* Makefile.am: Skip building grub-core and all bootcheck targets if
|
||||
!COND_real_platform.
|
||||
* include/grub/time.h: Don't include <grub/cpu/time.h> if GRUB_UTIL
|

is defined.
