Suppress parallel build in interfaces/ecpg/preproc/.
This is to see if it will stop intermittent build failures on buildfarmmember okapi. We know that gmake 3.82 has some problems with sometimesnot honoring dependencies in parallel builds, and it seems likely thatthis is more of the same. Since the vast bulk of the work in the preprocdirectory is associated with creating preproc.c and then preproc.o,parallelism buys us hardly anything here anyway.Also, make both this .NOTPARALLEL and the one previously added ininterfaces/ecpg/Makefile be conditional on "ifeq ($(MAKE_VERSION),3.82)".The known bug in gmake is fixed upstream and should not be present in3.83 and up, and there's no reason to think it affects older releases.
