[oe] Where do I override DISTRO_FEATURES?

I see. Fortunately I can require conf/distro/angstrom-v2012.x.conf in
my own distro config file.

It's a backwards compatibility thing: we're bound to gcc-4.5 (we have
kernel build issues with newer gcc versions; we're nailed to
linux-2.6.37 thanks to lack of support by Texas Instruments) which
fails to detect the correct version of binutils GOLD (LD would work)
and therefore misses critical features which break the build later on.
I won't, however, try to convince the Angstrom guys to further support
ancient toolchains and make gold optional again just because of TI's
laziness.

I'll try to set up a minimal config for a distribution based on
Angstrom, then, so I can fix up DISTRO_FEATURES. Thanks for your help,
Paul.

Regards,
Thilo
