[openib-general] [PATCH OFED-1.1-rc7] libehca configure: fix missing check of libsysfs

[Hoang-Nam Nguyen]

Hi Vlad!

As Michael indicated in previous email configure is a generated file
from autogen.sh. And I'm not sure if your packaging script does generate
it automatically when you build the whole OFED tgz-file.
The actual patches in configure.in and config.h.in are needed because
I got compile error like:
static declaration of ibv_read_sysfs_file() does not match previous
declaration in infiniband/driver.h
Thanks!
