The actual command line generated by is:

../dmd/src/dmd -conf= -I../druntime/import  -w -dip25 -m64  -g -debug 
-main -unittest generated/osx/debug/64/libphobos2.a -defaultlib= 
-debuglib= -L-lcurl -run std/stdio.d

So having this in the makefile:

* makes sure the library is built automatically

* links the right external libs

* makes sure command line options such as -dip25 are not omitted

* makes sure there's no interference from dmd.conf files

* links the correct library

* ...

So if your point was it can be done just worse, sure.
