PGXS on VPATH?

Hi,

Is PGXS on VPATH builds supported?  I was just testing tsearch2 and it
isn't working.  Note that I'm first standing on the builddir and it
doesn't work; then I'm back at the srcdir and it does work.

07:02  jovan tsearch2 2$ pwd
/pgsql/build/00orig/contrib/tsearch2
07:02  jovan tsearch2 0$ LANG=C make USE_PGXS=1
make: *** No rule to make target `tsearch.sql.in', needed by `tsearch2.sql'.  Stop.
07:02  jovan tsearch2 2$ cdsrc
07:02  jovan tsearch2 0$ pwd
/pgsql/source/00orig/contrib/tsearch2
07:02  jovan tsearch2 0$ LANG=C make USE_PGXS=1
sed -e 's,MODULE_PATHNAME,$libdir/tsearch2,g' tsearch.sql.in >tsearch2.sql
cp untsearch.sql.in untsearch2.sql
gcc -O2 -Wall -Wmissing-prototypes [...]
