Single dollar signs without variable reference are treated as literal
dollar signs by GNU Make if they are before a terminator, such as a line
ending or a comma in a function argument list. Let Kati do the same.
Consider the following Makefile
foo := $(subst a,$,bab)
test:
echo $(foo)
foo expands to b$b by replacing occurrences of 'a' by the literal
'$'. The command effective is then echo b$b, printing just 'b' unless
$b evaluates to something.
There was a test failing due to this missing corner case implementation
that is now fixed as well: testcase/subst2.mk
Further I added an explicit test case: testcase/simple_subst.mk to
preserve this corner case.
