[oe] chromium 29.0.1518.2 for armv7a

[Cestonaro Thilo]

Hey,

I'm trying to compile chromium from meta-browser for a armv7a SoC.
But it always failed with following error[1]. I fixed this bug with the 
appended patch and I had to remove
the extra cflag "-Wno-error=unused-local-typedefs" from the recipe to 
get it to compile.
But can someone have a look at the patch and tell why the hell this 
compiles and the original code not, please?

However the real problem[2] is, that whenever I try to start chromium on 
the armv7a machine, it segills right away. Even --help brings the sigill :/.
I've no idea how to fix such a problem; any comments?

Thx.

Greetings
Thilo
