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.
