    Export SHELL before invoking lineno.sh
   =20
    A user reported that building the sim failed, because their shell was
    not sh-compatible.  In particular, lineno.sh uses $SHELL to invoke
    another script.
   =20
    This patch arranges for SHELL to be exported when invoking lineno.sh,
    ensuring that the correct shell is used.
