I don't know what is going on with gdb and llvm, but I tried the 
upcoming gdb-7.3 and the message "Unable to read JIT descriptor from 
remote memory!" is back when llvm::JITEmitDebugInfo is set and 
libLLVM-3.0.so is loaded dynamically.

gdb-7.1 was broken, gdb-7.2 works, now gdb-7.3 code is broken again.
