[fuse-devel] [PATCH] Advertize the existence of some "configure" env vars.

[Fabrice B. <li...@gm...>]

Hello,

configure.ac can handle 3 useful environment variables:
MOUNT_FUSE_PATH, UDEV_RULES_PATH and INIT_D_PATH.  However, they are
largely undocumented (they do not appear when ./configure is run).

The below patch makes ./configure indicate that a default value is
used when the env var is not set, telling the user that she can change
it.
