If MAKETARS_SERIAL is set to "YES" or "yes", then the tar sets will be 

made in series, even if make's "-j" flag requests multiple parallel
jobs.  This is useful on systems that exhibit poor performance when
running multiple parallel disk-intensive operations.  The default is
MAKETARS_SERIAL=NO, which will obey the "-j" flag passed to the make
command.

Requested in tech-toolchain.  Reverts the change made in revision 1.56.
