Some modules .so are stripped while others are not

Hi there,

I wonder why some modules are stripped of their text symbols, others are not.

For example 

  >nm -D /opt/rad/lib/rlm_rest.so | grep -i " T "

gives the expected list for -g cflag.

  >nm -D /opt/cpr/lib/rlm_realm.so | grep -i " T "

doesn't show anything, even when using ./configure --enable-developer

How is this configured? I couldn't find the "magic"...

Thanks in advance
Till
