dependencies with @xx@ variables

[Joakim Tjernlund]

I got this rule in Makfile.am:
 ldadds_false = $(ldadds_cuappl)
 ldadds_true = $(ldadds_culess)

 common_LDADD += $(address@hidden@)

@CU_LESS@ is either true or false.

$(address@hidden@) is omitted in am__DEPENDENCIES_1 so
if any lib mentioned in ldadds_cuappl or ldadds_culess changes
no rebuild is generated.

if I change $(address@hidden@) $(ldadds_false) it makes it into
am__DEPENDENCIES_1 and a rebuild is generated.

Is the above a bug?
How do I workaround it?

I am using automake 1.10.2
