Compiler flag only works partly

[mathias-baumann-sociomantic]

I have the old D1 compiler installed an the new one using the name dmd2. When specifying

./dub --compiler=dmd2 -v

It shows me that for linking, it is using dmd instead of dmd2:

Linking...
dmd -of/tmp/dub/3351097566/ddox /tmp/dub/3351097566/temp.o -L-levent -L-levent_pthreads -L-lev -L-lssl -L-lcrypto

As far as I can see, this should be fixed indirectly on master (a3a20b5) by avoiding the separate compile/link in this case. Since the build system will probably be rewritten when (hopefully) something like dlang/dmd#1861 gets implemented, and if separate linking is not strictly needed, I would leave it at that.
