Here's a patch.  Should I send it to autoconf-patches instead?
I license this patch under the GFDL.  The commit message is public domain.

    Correct documentation for AC_ERLANG_SUBST_INSTALL_LIB_DIR
    
    Previously, the docs incorrectly stated that the default value was
    $ERLANG_LIB_DIR.  The default has always been $libdir/erlang/lib (at
    least as far as the git repo goes back).
    
    I didn't wrap the second isntance in a @code{} operator because it added
    some ugly extra quotes in the .info generated docs.
