[oe] I realy think we should upgrade PREFERRED_VERSION_glibc to 2.9 in conf/distro/include/sane-toolchain.inc

Hi guys,
   I think we should upgrade PREFERRED_VERSION_glibc from 2.6 to 2.9 in  
conf/distro/include/sane-toolchain.inc. The reasons are:

1. Most of distributions have upgraded their preferred glibc to 2.9 long  
time ago.
conf/distro/angstrom-2008.1.conf:PREFERRED_VERSION_glibc 		?= "2.9"
conf/distro/angstrom-2008.1.conf:PREFERRED_VERSION_glibc-initial 	?= "2.9"
conf/distro/jlime-2009.1.conf:PREFERRED_VERSION_glibc-initial = "2.9"
conf/distro/jlime-2009.1.conf:PREFERRED_VERSION_glibc = "2.9"
conf/distro/kaeilos.conf:PREFERRED_VERSION_glibc 		?= "2.9"
conf/distro/kaeilos.conf:PREFERRED_VERSION_glibc-initial 	?= "2.9"

 from the above, you can get to know that most distributions have upgraded  
their preferred glibc to 2.9 from 2008 ago.

Of course, there are still some distributions which uses old glibc. The  
only reason I guess is that we have not updated them for a long time. (for  
 from tinderbox, you can get to know that these distributions have not been  
built for a long time)


2. from tinderbox, you can see that the glibc-2.9 is well-tested, no  
glibc-2.6
http://tinderbox.openembedded.net/packages/?name=glibc&page=1

 from the above link, you can get to know that the glibc-2.9 not  
glibc-2.6.1 has had most testing.

3. the last reason is that I have built some projects with glibc-2.6,  
unless with the old binutils, the glibc-2.6 always failed to build.

So, I think it is the time to upgrade PREFERRED_VERSION_glibc to 2.9 in  
sane-toolchian.inc
