Although I haven't tried a build from scratch in a few weeks or so, I 
have one known problem with glibc 2.9. I wonder if it's just me or not. 
glibc 2.6.1 always works. On my armv4t board gpe-mini-browser2 always 
seg faults. I've tried different gcc and binutils combinations. However, 
glibc 2.9 on armv5te (imx) or armv7a (omap) work fine for me.
