configure: whitespace cleanup

In order to make it easier to keep the whitespace consistent in the
configure script, use the same style defined in devel/STYLE for
C/C++.

  Specifically, a line should begin with zero or more tabs followed
  by fewer than eight spaces.

Presumably this will be no more difficult for people editing configure
than for people editing the C and C++ code.
