[PATCH] Set preferred glibc to 2.10.1 in conf/distro/micro.conf

[Guo Hongruan]

* the preferred version of binutils of conf/distro/micro.conf is 2.19.51
* the preferred version of glibc is 2.6.1 which is defined in sane-toolchain.inc
* the ld produced by binutils-2.19.51 reports that it can not find the __begin symbol when linking with glibc-2.6.1

It would be really great if you could start to read emails too.

So now we now two ways to cure the symptoms but we have no idea about the 
underlying root cause.

Is it too much to ask what the actual error is? The __begin reminds me of a 
bug in the linker script Khem was pointing out?

I guess you are using latest binutils. There has been changes in ld
which surfaced this issue. So either you could switch back to using
older binutils like 2.18 or something. Or you could also port the patch
recipes/glibc/glibc-2.9/glibc-2.9-use-_begin.patch

That's the cause of the building failure. I think it is better to use the  
newer version of glibc that to port the patch to glibc-2.6.1

It takes quite a bit to validate a toolchain (gcc/binutils/libc) before
it is pushed as default preference. Dont use sword to kill a
fly. You could very well backport the one patch and keep using 2.6.1
if you want to upgrade make sure that its stable enough and tested
enough on some common architecuture/machines but as eglibc is default
libc for micro I wouldnt worry too much for glibc as it might not hit
all users of micro.

I have reproduced this bug many times. And I have validated this patch on  
arm, mips, x86 platforms, it did work OK.
By the way, the patch only changes the default glibc version of  
micro.conf, so it will not kill other distributions.

As eglibc is default libc for micro, this patch just added default glibc  
version, so it will not hit any users of micro using eglibc.
