My DMD ~master build gives linker error and IDK why

[Basile B. via Digitalmars-d-learn]

This is my script:

====
HOST_DMD=dmd
MODEL=64
cd dmd
make -fposix.mak MODEL=64 clean
make -fposix.mak ENABLE_RELEASE=1 MODEL=64 DMD=../dmd/src/dmd -j 5
cd ../druntime
make -fposix.mak MODEL=64 clean
make -fposix.mak MODEL=64 DMD=../dmd/src/dmd -j 5
cd ../phobos
make -fposix.mak MODEL=64 clean
make -fposix.mak MODEL=64 DMD=../dmd/src/dmd -j 5

cd ..
cp dmd/generated/linux/release/64/dmd bin-master/
cp phobos/generated/linux/release/64/libphobos2.a bin-master/libs/

When i compile a simple module with a main function and std.stdio 
as import i get:

But this used to work fine, this for months and months even 
recently i've cast a session where i build DMD master to show 
something about my IDE.
