Try not setting `silent-rules' in Makefile.am at all.  It is sufficient
to only use the macro AM_SILENT_RULES in configure.ac.

The setting in Makefile.am has been turned into an error because it
alone was not sufficient; and when the developer has to touch
configure.ac anyway, then there is little reason to build only part of
the tree with silent rules, so there is no reason to require changing
any Makefile.am at all.

Cheers,
Ralf
