Bug description:
  SRU Justification

  [Impact]

  Can't use ${VARIABLE} on config file with -Dvar=value

  Actually this is not a direct cause. but one of symptoms.

  It's affected from Trusty to Wily ( Precise is ok )

  [Test Case]

  set NFS server
    - /export/test1
    - /export/test2
    - /export/test-wily ( has README file )

  set NFS client
    - insert "/test /etc/auto.test" on the bottom of /etc/auto.master
    - insert "test autofs_nfs:/export/${TESTVAR}
    - run "automount -DTESTVAR=test-wily --pid-file=/var/run/autofs.pid -d -f -v"
    - go /test, run ll test
    - can see whole subdirectories on /export, should see only files in /export/test-wily

  [Regression Potential]

  [Other Info]

  After analyzing the codes and build,

  I found that it's ok with result of "make" command.

  but doesn't work with "debuild" command.

  so I suspected compile option

  I changed override_dh_auto_build part on debian/rules to below

  -----
  override_dh_auto_build:
          CFLAGS="$(CFLAGS) $(CPPFLAGS) -fgnu89-inline" \
          LDFLAGS="-Wl,-z,relro" \                                                                     <<
          dh_auto_build
  -----

  then debuild, it works

  with -symbolic-functions option, static global variable in shared
  library can't be used properly.. they lose some variables or element
  in list as I tested.

  I'm curious whether it's affected all other pkg.. because it's
  compiler option problem
