I posted a detailed workaround on www.xcept.com/tbirdcompile.html.
I hope it helps some folks, and I hope that somebody will be able to
figure out what the root cause is.
Have fun,

Why do you run ./configure directly in your source folder when using a
objdir? AFAIK this is wrong, just run make -f client.mk build, this will
also run configure (in your objdir).
