Careful with your m4 quoting here - by adding a dnl after the comma, the
leading whitespace on the next line is no longer stripped.  In turn, if
AC_LIB_HAVE_LINKFLAGS uses "m4_default([$2], [some default])", since $2 is
non-empty (although it is all whitespace), you no longer get the [some
default] action.  Perhaps that could be related to the issue you are hitting?
