[klibc] dash: parser: Fix backquote support in here-document EOF mark
[ dash commit c166b718b496da63c4df7a0972df2fc6cd38256b ]
Currently using backquotes in a here-document EOF mark is broken
because dash tries to do command substitution on it. This patch
fixes it by checking whether we're looking for an EOF mark during
tokenisation.
