libfoo.la is already going to be installed in `lib'

[Harlan Stenn]

I hope I didn't ask about this one already.

I have a Makefile.am that uses conditionals:

 foo/Makefile.am:
 if COND1
  libfoo = libfoo.la
 endif

 if COND2
  libfoo = libfoo.la
 endif

 ...
 lib_LTLIBRARIES = $(libfoo)

and when I run automake-1.6.3 on it I get:

 automake: foo/Makefile.am: `libfoo.la' is already going to be installed in
 `lib'

twice.

So how do I get automake to shut up?
