This is the correct behavior. We shouldn't relocate binaries that use
host's dynamic loader.

Can you please run the installer script with "-R" so it doesn't perform
any relocation on binaries, and then:
readelf -p ".interp"
/usr/local/oecore-x86_64/sysroots/x86_64-angstromsdk-linux/usr/bin/armv7ahf-vfp-neon-angstrom-linux-gnueabi/arm-angstrom-linux-gnueabi-gcc
It looks like the default dynamic loader path of the toolchain binaries
start with /lib* or /usr/lib* which is not quite right... It should be:
${SDKPATH}/sysroots/${SDK_SYS}.
