[Buildroot] "undefined reference to 'raise'"

[Shai Lifshitz]

 I try to build u-boot with buildroot with the following configuration 
flags:

BR2_arm=y
BR2_arm926t=y
BR2_ARM_EABI=y


I did look in google, but found only two solutions:

1) add a patch (which does not exist any more on the net)
2) write an empty 'raise' function (which quite worries me not to treat 
the division by zero)

following is the u-boot compilation error:

if someone can help me with this one, I'll be very grateful

Mmmm... google with "undefined reference to 'raise'" ?
