libsensors: Take into account distribution LDFLAGS (Patch from Didier Roche).

From: Didier Roche <didrocks@ubuntu.com>

Hi lm-sensors developer,

It would be great if lm-sensors can take into account distribution
LDFLAGS so that exported variables change linker behavior.

For instance, ubuntu uses -Wl,-Bsymbolic-functions. Taking this patch
will enable us to just sync from debian on this package.

In Ubuntu, we've applied the attached patch to achieve the following:

  * handle default ubuntu LDFLAGS for linking option (LP: #321632)
    - Remove the old hack directly pushed in lib/Module.mk (now
      lib/Module.mk if from pristine source)
    - add debian/patches/07-use-LDFLAGS.patch to take LDFLAGS into account

Debian and Ubuntu thought you might be interested to handle this
directly upstream.
