[arm-gnu] undefined reference to bswapsi2

[Shalabh Agarwal <slowreader@xxxxxxxxx>]

Hi

I'm just trying to build a 2.6.17 Linux kernel for an arm target on a Ubuntu
system.

I get an undefined reference to bswapsi2 even though it is present in libgcc

that comes with the CodeSourcery package.

I must be doing something simply wrong. Can anyone help?

thanks
Shaun
