[Bug libmudflap/24420] New: mudflap doesnt work with DSOs?

["SLTxLQEc4vuR5kMzK at anime dot net" <gcc-bugzilla at gcc dot gnu dot org>]

dlopen() on a -fmudflap -lmudflap'd DSO fails:
Sys_LoadDll(/home/wolf/.etwolf/etpro/qagame.mp.i386.so) failed:
"/usr/lib/libmudflap.so.0: undefined symbol: _start"

standalone binaries work fine.
