The shell function make_system_path_relative_to_its_root() does not work
on Cygwin due to path mapping (e.g. /boot/grub/ is actually

This patch adds '-t prefix' to grub-probe. It prints result from
grub_get_prefix() which is already extended for Cygwin (svn rev 1584).
The result is used in make_system_path_relative_to_its_root(). This
keeps the platform dependent code in getroot.c.

* util/grub-probe.c (enum): Add PRINT PREFIX.
(probe): Add PRINT_PREFIX, prints result of
grub_get_prefix ().
(usage): Add `prefix' to `-t' usage text.
Add some '\n' to avoid excess long lines.
(main): Add check for `-t prefix' option.
This is different than the usual grub-probe usage in that it doesn't operate
on a device. Perhaps it would make sense to add the functionality you want in
a separate utility?
OK, probably /usr/bin/grub-prefix ?
Drawback: getroot.c contains also grub_guess_root_device() etc, so a
grub-prefix program would require most of the objects grub-probe requires.
Put grub_get_prefix() in a new util/getprefix.c ?
Or handle those platform dependencies in update-grub_lib.in itself. Can
be done by a conditional call to 'cygpath' utility. This conditional
must then be removed for the other platforms when generating
update-grub_lib.
