Modified the sky130 Makefile to prevent the "install" from running
concurrently on PDK variants A and B if the "-j" option is passed
to "make" to enable a multithreaded build. If concurrent, then
files in variant B may install before variant A, preventing the
files from being compared and replaced by symbolic links. Note
that this does not invalidate anything in the PDK, but it will make
the build different from run to run.
