editors/openoffice-*: build fix for 13.X and 14.XHEADmain

Another attempt at fixing the intermittent build failures on FreeBSD
13.X and 14.X.  No failures are observed on 15.X.  The failures depend
on system load and are not affected by MAKE_JOBS_UNSAFE=yes.

The failures are caused by nm failing with "Invalid argument".
nm --version reports "nm (elftoolchain r3769)" on 13.X and 14.X,
but
  llvm-nm, compatible with GNU nm
  LLVM (http://llvm.org/):
    LLVM version 19.1.7
    Optimized build with assertions.
on 15.X.  llvm-nm is available on 13.X and 14.X, and does not exhibit
the failure.  The root cause is unknown.

Switch many uses of nm to llvm-nm.

Re-enable parallel builds.
