Platform does not compile with linaro gcc 4.4

[Alexander Sack]

unitialized variables exposed in dalik cause build error when building with linaro gcc 4.4 in:

guess fixing for gcc 4.4 and validating that it works should be first step for 4.5 and 4.6 later on.

since 4.5 is really picky and since we use google 4.4 toolchain by default atm, fixing this with linaro 4.4 should be first step i guess and should definitely be tried for 11.06

We're not going to ship an official build with 4.4 but a build exists and has been tested. See: https://wiki.linaro.org/Platform/Android/Builds/Wip/Build1AsacLebPandaGccLinaro4.5Noprelink for build info and results.
