rpm macros: wrapped a long line

3 backslashes:
the last one makes the rpm macro continue on the next line
  and preserves the newline for the preceding two
the first two pass thru rpm to the shell as one
  to escape the shell newline
rpm macros: Use "make check VERBOSE=1"

so that build failures are easier to debug from the log alone
