I can confirm the problem with 4.5.1 on x86_64-linux-gnu.

Indeed, the `mflib' spec lacks `-lmudflap':

$ gcc -dumpspecs |grep -A2 -E '(mflib|link_command)'
*mflib:
%{fmudflap|fmudflapth: -export-dynamic}

--
*link_command:
%{!fsyntax-only:%{!c:%{!M:%{!MM:%{!E:%{!S:%(linker)
%{fuse-linker-plugin: -plugin %(linker_plugin_file)
-plugin-opt=%(lto_wrapper) -plugin-opt=%(lto_gcc)
%{static|static-libgcc:-plugin-opt=-pass-through=%(lto_libgcc)}
%{static:-plugin-opt=-pass-through=-lc} %{O*:-plugin-opt=-O%*}

Note that threaded programs need -lmudflapth instead of -lmudflap.

The driver should add correct version of libmudflap automatically, or you'll
get bug reports from users who link the wrong version in.

Alternatively, libmudflap could use weak unresolved pthread_* symbols, so that
a single version of libmudflap works in both threaded and non-threaded
environment.

Maybe it never worked as stated in the documentation, but then either the 
manual should be changed or libmudflap should be automatically linked.

In my opinion libmudflap should be automatically linked, linker command lines 
are already long enough.
