I add configure.ac and build.
But, I can't find difference between using of -Wl,-as-needed and not using.

Use -Wl,-as-needed :
/opt/ats/bin$ ldd -u -r traffic_server
Unused direct dependencies:
linux-vdso.so.1

Not use -Wl,-as-needed :
/opt/ats/bin$ ldd -u -r traffic_server
Unused direct dependencies:
linux-vdso.so.1

Could you describe more details?

 We should pass {{-Wl,-as-needed}} to the linker on Linux to get it to strip 
 unused libraries. The equivalent Darwin option is {{-Wl,-dead_strip_dylibs}}.
