[PATCH] sane-toolchain.inc: Make gcc 4.5 & eglibc 2.12 as default sane versions

[Khem Raj]

GCC 4.5 has been tested quite a bit and so is eglibc 2.12 in SHR
and developers.

Probably not on ARMv5 ;) There 5/3 == 3 holds and ld.so crashes due to
related errors.

That bug seems to be specific to --enable-target-optspace, which (afaik)
isn't selected for armv5 by the current recipes.  Are you actually
seeing that bug on a toolchain built with the settings in OE?

I have local customizations but I can not see in

$ git grep -i optspace

on vanilla OE where optspace is disabled for armv5.

yes there are few other bugs open against gcc 4.5 Interestingly I did
not hit this bug while building images for qemuarm which is armv5. Is
it common enough occurring problem that we should not use gcc 4.5 ?

Oh yes, right, it does seem to be enabled globally in
gcc-configure-common.  I had somehow read that conditional backwards
when I looked at it before.

If that's the case then yes, obviously this needs fixing before gcc 4.5
is made the default.  The slightly odd thing is that the corresponding
conditional in lib1funcs.asm seems to have been there basically forever
(since r77171) and it isn't obvious to me why it has suddenly broken
now.

sorry; my fault.  I applied a broken patch from [1].
