daomake - fix help generation by preventing sigsegv due to wrong library ordering
Currently during building, the environment variable LD_LIBRARY_PATH should ensure, that the newly compiled libraries are taken into account. Unfortunately, the GNU C dynamic linker uses a weird messy algorithm to determine the proper order and therefore, first the system libraries are searched and then the LD_LIBRARY_PATH. This can be prevented by adding another attirbute to the ELF header called DT_RUNPATH.
GCC provides the --enable-new-dtags option for this purpose. I don't know how about other compilers :(
For unix systems, the patch is straightforward - e.g. with sed -i -r 's|-Wl,-rpath=|-Wl,--enable-new-dtags,-rpath=|' tools/daomake/platforms/unix.dao.
The sigsegv when run in valgrind:

This looks weird. No way should the JIT module be loaded here. Please try a clean build to see if it still happens. Please also try strace or (dtruss on mac) to check the paths of the loaded modules. Thanks.

I think it's pretty clear now what is going on. First the treacherous GNU C linker algorithm loads the old system library /usr/lib/libdao.so, then ./dao.conf is read (the one I'm using contains cpu =2 and jit =yes) which explains JIT and first then the libdao_help.so library is read from LD_LIBRARY_PATH.
By the way, I'm always compiling with newly fetched git directory, so there are no old files potentially causing harm.
