Unconditionally invoke AM_SILENT_RULES macro
Unconditionally invoke AM_SILENT_RULES macro

We require at least Automake 1.14.1. AM_SILENT_RULES was
introduced by Automake 1.11.

So the m4_ifdef check for availability of AM_SILENT_RULES
only made sense when our Automake version requirement was
less than 1.11, and can be removed now.
