description:
While gcc may automatically add -fexecptions to c++ code it will only do that
for files named .cc or .C. _eh gets generated into a .c file so we need
explicit rules for it's targets (.o .po and .so) to compile it correctly.

Without this exceptions just plain don't work. Nothing ever gets caught.
