cross-build fails, target host:powerpc, build host:x86_64

[Hector Oron]

Hi Alan,

  Just for the mail logs and you to know that this issue was isolated
in Debian compiler and the following patch fixed it, but it was not
applied into our tree.

2009-10-16  Tristan Gingold  <gingold@adacore.com>

	* configure.in: Bump version to 2.20.0
	* Makefile.am (RELEASE): Unset.
	* configure, Makefile.in: Regenerate.
