[Buildroot] Error building qt-embedded in buildroot-20080618 snapshot

[Thiago A. Corrêa]

Hi Simone,

    I'm able to build qt-embedded for avr32 using the googlecode
buildroot, and actually use it in custom packages. I do know for a
fact that upstream buildroot qtopia/qt-embedded is quite broken, but I
don't recall of issues in it that would cause this problem in
particular.

    Others have seen problems with pthreads in newer uClibc, you might
want to try 0.9.28 instead. I will try to build x86 qt-embedded on my
tree to see if it works as well.

Kind Regards,
    Thiago A. Correa
