Hash :d747a66a Message :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.
