commit 381c4b69c7e8b452f4d3de2f8214e6e5f6a9abe7

*problem
Compile mkelfimage-native failed if host does not 
install libz.
>>log<<
...
fatal error: zlib.h: No such file or directory
/usr/bin/ld: cannot find -lz
...

*analysis
If the host does not install libz, bitbake mkelfimage 
works well but mkelfimage-native failed, because
mkelfimage-native find libz from host dir, not from 
the staging directories.

*solution
1.Config LDFLAGS and LDFALGS_class-native in bb 
file to let mkelfimage and mkelfimage-native 
find libz and zlib.h from the staging directories.

2.Modify confiugre.ac to let makefile find libz 
and zlib.h by CFLAGS and LDFLAGS. Because the 
original Makefile don't make use of them.
