We want to see any newly introduced automake problems immediately, so
enable automake warnings with "-Wall -Werror".

Use "git clean" as a check-in test to help expose problems with
missing or untracked files.

Also, enable quiet building to make new compiler and linker warnings
easier to see.  With "make -s" we now get:


Making all in nsdbparams
  CC     main.o
  CCLD   nsdbparams
Making all in resolve-junction
  CC     main.o
  CC     privilege.o
  CCLD   resolve-junction


making warnings stand out clearly.

Unfortunately I don't see a way to make silent builds the default
behavior, though: you still have to request it explicitly via:

  ./configure --enable-silent-rules
