Actually it would be easiest for me if the last 5 lines of
https://github.com/Angstrom-distribution/meta-angstrom/blob/master/conf/distro/angstrom-v2012.x.conf
would not be

DISTRO_FEATURES += "${LDISGOLD}"
LDISGOLD_arm = "ld-is-gold"
LDISGOLD_x86 = "ld-is-gold"
LDISGOLD_x86_64 = "ld-is-gold"
LDISGOLD = ""

but instead be

DISTRO_FEATURES += "${LDISGOLD}"
LDISGOLD_arm ?= "ld-is-gold"
LDISGOLD_x86 ?= "ld-is-gold"
LDISGOLD_x86_64 ?= "ld-is-gold"
LDISGOLD ?= ""

But anyways, I decided to fix the gcc-4.5-cross-initial build.

Regards,
Thilo
