Subject: [PATCH] Fix makedefs

1)remove RANLIB, SYSLIBS, AR and get them from env.
2)reference sysroot when searching header files
3)include sysroot path instead of absolute include path
for Linux2 and Linux3 systems.
4)for non-native build, search STAGING_BASELIBDIR/LIBDIR
  native build, search host library path for nsl and resolv library
  which comes from libc

Upstream-Status: Inappropriate [embedded specific]
