To clarify, It's not caused by the sourcery external toolchain, and it'll
likely be hit with any external toolchain, not just the Sourcery one.

The fundamental issue is mux-server wasn't obeying LDFLAGS from the
buildsystem. That is a bug regardless. It just only generates a QA error
with toolchains that didn't have their GNU_HASH set by default (the
internal toolchain does so).

This is fairly common, and we've been submitting fixes for these to a
variety of layers ovr the years. Due to the default behavior of the
internal toolchain, not obeying LDFLAGS is easily missed / silent. I might
propose changing that default behavior to poison the build to help make
these more visible, at some point.
