Hi Vladimir!

Created a bugzilla as libehca could not be found by libibverbs,
http://openib.org/bugzilla/show_bug.cgi?id=285.
I guess I was not precise enough in that configure does not
only check libsysfs, but also generates corresponding define
HAVE_SYSFS_LIBSYSFS_H in config.h to enable/export openib_driver_init()
from libehca. So we really need configure.in and config.h.in
to enable libehca for user space. Without them ehca configure still
goes through.
