Is there any way to add extra values to the base LIBS variable in a
Makefile.am, then?  For CFLAGS, you can use AM_CFLAGS, but there doesn't
seem to be an equivalent for LIBS.

The above just about works, but I have a makefile with 35 entries in
_PROGRAMS, some of which are conditional, and I want to add the same value
to LIBS for each of them.  CVS automake gives errors of "LIBS was set
with `+=' and is now set with `=' ".

I don't really want to have 35 lines in my makefile saying
prog1_LDADD = $(MYLIBS)
prog2_LDADD = $(MYLIBS)
...
prog35_LDADD = $(MYLIBS)

Being able to do "AM_LIBS = $(MYLIBS)" would be much nicer.

In fact, I'll state this as a feature request: I'd like to be able to set
values for AM_LIBS and have these used wherever LIBS is used.
