Use .NOTPARALLEL in ecpg/Makefile to avoid a gmake parallelism bug.
Investigation shows that some intermittent build failures in ecpg are the
result of a gmake bug that was reported quite some time ago:
http://savannah.gnu.org/bugs/?30653
Preventing parallel builds of the ecpg subdirectories seems to dodge the
bug. Per yesterday's pgsql-hackers discussion, there are some other things
in the subdirectory makefiles that seem rather unsafe for parallel builds
too, but there's little point in fixing them as long as we have to work
around a make bug.
Back-patch to 9.1; parallel builds weren't very well supported before
that anyway.
