Comment (by hinder):

 Try adding -rdynamic to LDFLAGS:

   http://gcc.gnu.org/onlinedocs/gcc/Link-Options.html

 This was necessary for me to get this to work.  The patch uses
 undocumented GLibC hacks, so we should test it on several exotic
 architectures before applying - it might need to be disabled if certain
 features are not available.  There is no platform-independent or supported
 way of doing this, according to Justin's comments.

 We could consider adding -rdynamic by default to LDFLAGS in the flesh,
 though I don't know what the consequences of this would be.
