I committed the important part of this:
The configure.ac change caused mysterious failures if the AC_MSG_ERROR([dlfcn.h is missing]) statement was actually executed. I came up with a workaround, but in the end left that part of the change out completely, because I don't think it makes sense to #error just because some poorly behaved applications that use RTLD_DEEPBIND might break.
