Patch to doc/install.texi below, which I'll install as part of the
patch.  It looks like Linux targets already required binutils 2.15,
which includes .hidden support.  I just made it mandatory for all
PowerPC targets; I'm happy to lower it for PowerPC targets generally (to
pick up .hidden support) and still require 2.15 for Linux targets.

Gerald, is the patch OK?  David/Alan, OK to require 2.15 for all PowerPC

Yup, silly me.  I'll really delete it when I commit this patch.


	* doc/install.texi (powerpc-*-*): Require binutils 2.15.
	(powerpc*-*-linux-gnu*): Describe.
