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.
