commit 673d8593b7ef274dadbfff97fd641e3c563fc716
Author: Tony Cook <t...@develop-help.com>

check --whole-archive is supported before using it
netbsd for pre 4.6 gcc requires --whole-archive to build shared
libraries, but this is rejected and not required in 4.6.0.
Simply changing the option to -Wl,--whole-archive works on gcc 4.6.0
but fails for the system cc on NetBSD 5.1/x64.
