But that's a problem that can be solved.

# turn $1 into a string suitable for a shell variable name
func_tr_sh ()
{
 ... # typically forks, except maybe with bash ${var/subst/repl}
}

# when treating $dlprefile, save the corresponding .la file name:
func_tr_sh "$dlprefile"
eval "libfile_$tr_sh_result=\$corresponding_dotla_file"

# later, when searching for the .la file, test libfile$tr_sh_result
# for contents

What do you think?
