Makerules: fix MAKEFLAGS assignment for upcoming make-4.4 [BZ# 29564]
|
|
|
|
|
|
|
|
|
|
|
|
make-4.4 will add long flags to MAKEFLAGS variable:
|
|
|
|
|
|
|
|
|
|
|
|
* WARNING: Backward-incompatibility!
|
|
|
|
|
|
Previously only simple (one-letter) options were added to the MAKEFLAGS
|
|
|
|
|
|
variable that was visible while parsing makefiles. Now, all options
|
|
|
|
|
|
are available in MAKEFLAGS.
|
|
|
|
|
|
|
|
|
|
|
|
This causes locale builds to fail when long options are used:
|
|
|
|
|
|
|
|
|
|
|
|
$ make --shuffle
|
|
|
|
|
|
...
|
|
|
|
|
|
make -C localedata install-locales
|
|
|
|
|
|
make: invalid shuffle mode: '1662724426r'
|
|
|
|
|
|
|
|
|
|
|
|
The change fixes it by passing eash option via whitespace and dashes.
|
|
|
|
|
|
That way option is appended to both single-word form and whitespace
|
|
|
|
|
|
separated form.
|
|
|
|
|
|
|
|
|
|
|
|
While at it fixed --silent mode detection in $(MAKEFLAGS) by filtering
|
|
|
|
|
|
out --long-options. Otherwise options like --shuffle flag enable silent
|
|
|
|
|
|
mode unintentionally. $(silent-make) variable consolidates the checks.
