The whole libmysqld-pic package is unnecessary in 5.6. MySQL is built with  
-fPIC by default, so we should just drop it.

Files in BUILDDIR and BUILDDIR_PIC should be put there by CMake. I don't  
see why it should behave differently for -pic. There have been race  
conditions in the rules file before. Maybe you hit one?
