directfb fails to build from source with Linaro toolchain

[Michael Hope]

Seen with gcc 4.4.4-6ubuntu5~ppa2 and directfb 1.2.10.0-4ubuntu1.

I suspect this is a generic ARM issue. The error is a missing prototype when compiling the ARM specific Davinci driver.

I can build *.deb packages by gcc 4.4.4-7ubuntu1~ppa2 and directfb-bin_1.2.10.0-4ubuntu2 *without* any errors on ARMEL beagle board. Let me know if error is still there.
