Building with gold does cut the build time of the chromium component 
back down.

binutils 2.25, bfd:  00:47:51, 00:44:24, 00:44:25
binutils 2.26, bfd:  02:07:45, 02:09:31, 02:02:42

binutils 2.26, gold: 00:43:49, 00:45:18, 00:42:51


But the only way I could get it to work was to manually perform the 
following steps:
$ cd <oe tmp dir>/sysroots/<native sysroot>/usr/bin
$ ln -s <cross toolchain prefix>/<cross toolchain prefix>ld.gold ld.gold

where:
   <native sysroot> = x86_64-linux
   <cross toolchain prefix> = x86_64-poky-linux

to give:
$ cd <oe-tmp-dir>/sysroots/x86_64-linux
$ ln -s x86_64-poky-linux/x86_64-poky-linux-ld.gold ld.gold

Maybe I can play with the recipe a bit more to get this to work 
"automatically"; maybe by setting the LD environment variable 
differently or something.

But, as I said before, the last time I tried booting a gold-linked image 
on the minnow grub2 refused to work :-(
