[oe] [meta-browser] Chromium and gold linker

[Denys Dmytriyenko]

Khem, et al,

I couldn't find below patch being discussed on this mailing list before it got 
merged:

https://github.com/OSSystems/meta-browser/commit/62e323848f569c4cdea5567b1917ce006d7705af

According to the layer README, openembedded-devel is the official mailing list 
to submit patches. I understand that github pull request is a nice shortcut, 
but it prevents others from seeing and commenting on the patches...


My issue with this change is that it makes an assumption of using OE-built 
toolchain. It now breaks external toolchains like this:
