+Don't embed the path to the build-time POSIX shell as this will be
+$TMPDIR/hosttools/bash, which is no good on the target.
+
+Instead default to /bin/sh but allow it to be set in the environment.
+
+This isn't really upstreamable but I filed a bug at
+https://gitlab.com/gnutls/gnutls/issues/807 and hope a proper fix will be
+integrated.
