libpjsip: disable parallel build

The libpjsip package has build issues on the autobuilders that look
like parallel build issues. These issues seem to be extremely hard to
reproduce, so let's disable parallel build and see if this fixes the
issue.

The suspect error message is:
  ...-ld: cannot find -lpjsua
  collect2: error: ld returned 1 exit status

Some of the failures:
