[m-dev.] diff: AS configure bug in 0.9

[Tyson Dowd]

Hi,

Here's a fix for that configure bug in 0.9.  I'll commit it right now
on the version-0_9_x branch and the main development line.

===================================================================


Estimated hours taken: 0.75

Fix a bug that was causing configure to substitute the wrong value for
AS if it was run a second time.

configure.in:
	Move setting AS to after the test.  If we set it during the test
	we won't set AS if we don't perform the test (for example, if we
	get the value of the test from config.cache).
