The PHP_OUTPUT macro was introduced in the very early phase of the build
system due to AC_OUTPUT handling issues in the old Autoconf versions
before the AC_CONFIG_FILES, AC_CONFIG_COMMANDS etc were introduced with
the AC_OUTPUT signature without arguments. The PHP_OUTPUT was also
helping Makefile.in back then being properly generated based on whether
all files were generated or only some (when using the obsolete
CONFIG_FILES=... ./config.status invocation instead of the new
./config.status --file=...). Another issue is that PHP_OUTPUT can't be
used by extensions when using phpize.
This replaces the PHP_OUTPUT invocations with default AC_CONFIG_FILES.
The obsolete "REDO_ALL" feature at the config.status invocation is also
removed with a simpler unconditional generation.
In phar extension the "ext/phar" is replaced with $ext_dir variable to
be able to use phpize.
