A number of testsuite problems

[B. Kosnik]

-rw-rw-r--    1 bkoz     bkoz           48 Jun 27 11:13 tmp_setbuf2
-rw-rw-r--    1 bkoz     bkoz          95M Jun 27 11:36 tmp

It is rude to have huge files around after make check. If you run "make
clean" in the testsuite directory, they'll be cleaned out. Perhaps they
should be deleted after the test finishes.

Cannot reproduce. I do have LD_LIBRARY_PATH set to the build dir though.

Cannot reproduce.
