Test Env:
Fedora release 17 (Beefy Miracle)
Linux version 3.6.6-1.fc17.x86_64 (mockbuild@)

*problem
running bitbake as the following sequence:
$bitbake tiff-native
$bitbake ghostscript-native
>>error log<<
libjpeg.so.8, needed by libtiff.so, not found
libtiff.so: undefined reference to `jpeg_set_defaults@LIBJPEG_8.0'
collect2: error: ld returned 1 exit status
...

*analysis
1. Running bitbake tiff-native, the libtiff and
libjpeg are populated to the staging native
directories.

2. If the host doesn't install libjpeg, 
the configure of ghostscript-native tests the
existance of libtiff which is located at staging
directory but libjpeg is not found by configure.

3. Even though we could modify configure to let
ghostscript-native link to libjpeg which is only
located at the staging native directories, but it
still can't load the lib when you run the mkromfs
which is created by ghostscript-native. The 
mkromfs needs libtiff and libjpeg to compile
ghostscript. That means "bitbake ghostscript" is
failed.

*resolution
Modify the configure of ghostscript-native, explicity
disable libtiff.
