Check for dladdr(), rather than assuming we have it if we have RTLD_DEFAULT
Unfortunately, Cygwin defines RTLD_DEFAULT (for glibc compatibility), but can't
provide dladdr(), so add a check for dladdr()
Since I don't think scons is ever used to build for Cygwin, just set HAVE_DLADDR
in SConscript, assuming that if we have RTLD_DEFAULT, we have dladdr().
