+poco: fix parallel build
+
+The makefile rule for generating objects implicitly depends on the existence
+of the containing directory. The makefile dependecies do not reflect this,
+however. Instead, the final compilation producs depend on one of libdirs,
+bindirs, or static_bindirs, which in turn depend on objdirs. This breaks
+parallel build since the objdirs target may not complete before the object
+files build starts as follows (abbreviated):
+
+make[2]: Entering directory `/home/test/test/output/build/poco-1.4.3p1/Zip'
+mkdir -p /home/test/test/output/build/poco-1.4.3p1/Zip/obj/Linux/powerpc/release_static
+mkdir -p /home/test/test/output/build/poco-1.4.3p1/Zip/obj/Linux/powerpc/debug_static
+mkdir -p /home/test/test/output/build/poco-1.4.3p1/Zip/obj/Linux/powerpc/release_shared
+mkdir -p /home/test/test/output/build/poco-1.4.3p1/Zip/obj/Linux/powerpc/debug_shared
+** Compiling src/AutoDetectStream.cpp (release, shared)
+...
+Assembler messages:
+Fatal error: can't create /home/test/test/output/build/poco-1.4.3p1/Zip/obj/Linux/powerpc/release_shared/AutoDetectStream.o: No such file or directory
+
+Add direct dependency on the objects directories to fix this.
