*/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.
