Remove tabs embedded in strings used for formatting output (#515)

Files gcfinal.c and testool.c both contain literal TAB characters embedded
in printf() format strings in an attempt to align output.
The output formatting depends on the user's simulated tab settings and
therefore may not produce the expected results.

The output formatting is rewritten to make tab characters unnecessary.
