*/c_src/Makefile*: Support parallel make
Create directories first, not within implicit rules. If two 'install' instances runs at the same time attempting to create a directory, one of them may fail with an "File exists" error. I tried to use order-only prerequisites to create the directories, but run into two problems: First, order-only prerequisites are only implemented in Make 3.80 and later. Second, on a computer running Solaris/Intel 2.8 (with Make 3.80), order-only prerequisites seemed to work like ordinary prerequisites, causing targets to be re-built if the timestamp for the directory changed. Therefore, using a shell command to run mkdir seems to be the more portable solution.
