m4: rework silent-rules macros to avoid double expansion Fixes automake bug https://bugs.gnu.org/32868. The AM_SILENT_RULES macro defines all the silent-rules related setup. It's also called by users to change the default verbosity level. This leads to a quirk where automake calls it, expands the full context, and then users call it, and it's fully expanded again. Instead, let's rename AM_SILENT_RULES to _AM_SILENT_RULES and move the initialization logic to late in the configure stage. This allows the user-centric AM_SILENT_RULES call to expand into a single line to set the default verbosity. * m4/init.m4: Switch to _AM_SILENT_RULES. * m4/silent.m4: Rename AM_SILENT_RULES to _AM_SILENT_RULES. Delay evaluation of AM_SILENT_RULES to the end. Define new AM_SILENT_RULES to set default rules verbosity. * t/silent-defaults.sh: New tests. * t/list-of-tests.mk: Add t/silent-defaults.sh.
