I'm surprised there is no warning with CFLAGS; it appears this warning
is issued for mumble_SOURCES, LIBADD, LDADD, LDFLAGS and DEPENDENCIES
only.

If you were to later add a program called TEST, then the results could
be surprising.  But you can certainly ignore the warning if you'd like.

Alternately you can perhaps use a different name that does not conflict
with the Automake naming structure.  Perhaps LDFLAGS_FOR_TEST?

You can disable the warning outright with -Wno-syntax (but this might
disable more than you'd like).

Finally, this warning is not issued for variables substituted by configure.
