Jeff Squyres 9334abc474 Makefile: fix problems with static linking
Avoid a problem with double-derefence of a variable macro name (i.e.,
a macro with part of its name from an AC_SUBST, such as
```$(foo@BAR@baz)```.

In what might be a bug in Automake 1.14.1, if you do a pattern like
this:

```makefile
lib_LTLIBRARIES = lib@A_PREFIX@a_lib.la
noinst_LTLIBRARIES = lib@A_PREFIX@a_noinst.la

lib@A_PREFIX@a_lib_la_SOURCES = a.c

lib@A_PREFIX@a_noinst_la_SOURCES = $(lib@A_PREFIX@a_lib_la_SOURCES)
```

Then in the resulting Makefile, the value of
```$(lib@A_PREFIX@a_lib_la_OBJECTS)``` will be *blank* (when it really
should be ```a.o```).

To workaround this potential bug, I've simply avoided doing
double-derefences like this, and effectively set the second
```_SOURCES``` line equal to ```a.c``` (just like the first
```_SOURCES``` line).

Fixes #250.

# To simplify components that link to this library, we will *always*
# have an output libtool library named libmca_<type>_<name>.la -- even

# necessary in component Makefile.am's that link to this library).
# Hence, if we're creating a noinst version of this library (i.e.,
# case 2), we sym link it to the libmca_<type>_<name>.la name
# (libtool will do the Right Things under the covers). See the
