I have an Olimex imx233-olinuxino-maxi that I build for and test regularly
(arm926ej-s, ARMv5).

Yesterday I performed two builds from master with the following configuration:

	Build Configuration:
	BB_VERSION           = "1.40.0"
	BUILD_SYS            = "x86_64-linux"
	NATIVELSBSTRING      = "opensuseleap-15.0"
	TARGET_SYS           = "arm-oe-linux-gnueabi"
	MACHINE              = "imx233-olinuxino-maxi"
	DISTRO               = "nodistro"
	DISTRO_VERSION       = "nodistro.0"
	TUNE_FEATURES        = "arm armv5 thumb dsp"
	TARGET_FPU           = "soft"
	meta-freescale       = "master:08173f472244817b85fe4af8ab2add7a0090b122"
	meta-fsl-arm-extra   = "master:b4d2c8462220e7038adffc0a151767ef8da07c5d"
	meta                 = "master:aeaca9bb1b1c8bf44818945dc4b2cbd6d4b5cef2"
	meta-oe
	meta-python
	meta-networking      = "master:24dd9328f7ec964bbad25b7061366f9f2ff6194d"

Both builds explicitly included gobject-introspection.

The first build was done as-is (i.e. using the bfd linker). The second build
had the following in conf/local.conf:

	DISTRO_FEATURES_append = " ld-is-gold"

The default build succeeded. The gold build failed as expected while running
qemu trying to build gobject-introspection.

The good build boots on the hardware and runs fine (as far as I can tell):
