I am trying to build dmd such that it will work on older versions of
GNU/Linux as well as newer versions with a single binary. This requires
some special attention for libc++ and lib_gcc, (or a link loaded wrapper
script)
I have proceeded like this to start off:

Which works assuming you compile it on redhat 3 and then it is upward
compatible (glibc wise). But objdump and the other tools also need
similar treatment, but I can't seem to find their source.
