When building sed with musl-libc (./configure CC=musl-gcc),
the new valgrind test fails (newline-dfa-bug.sh).

I suspect this is a problem with musl/valgrind interaction
and not a problem in sed/dfa - but other suggestions are welcomed.

The file 'musl-sed-dynamic-DFABUG.valgrind.log' contains
the error as appears in 'make check' logs.

The file 'musl-sed-dynamic-Q.valgrind.log' contains
the output of running:
  valgrind ./sed/sed -Q
It is the same error as the dfa test file, which leads me to think
it has nothing to do with sed/dfa.

I've also build sed with musl and static linking.
Testing the DFA bug results in a very large valgrind report.
The file 'musl-sed-static-DFABUG.valgrind.log.xz' contains the
first 1000 errors (warning: it expands to ~600KB).

Running again 'valgrind ./sed/sed -Q' still results
in valgrind warnings ('musl-sed-static-Q.valgrind.log').
