Change the use of a non-existing variable added in my
0b6d0bc924 (Makefiles: add and use wildcard "mkdir -p" template,
2022-03-03) to use the hardcoded whitespace padding for "QUIET" rules
instead. The wspfx_SQ was left from an earlier (rebased out) commit
preceding 0b6d0bc9246[1].

### Remove GNU make implicit rules
|
|
|
|
## This speeds things up since we don't need to look for and stat() a
|
|
## "foo.c,v" every time a rule referring to "foo.c" is in play. See
|
|
## "make -p -f/dev/null | grep ^%::'".
|
|
%:: %,v
|
|
%:: RCS/%,v
|
|
%:: RCS/%
|
|
%:: s.%
|
|
%:: SCCS/s.%
|
|
|
|
## Likewise delete default $(SUFFIXES). See:
|
|
##
|
|
## info make --index-search=.SUFFIXES
|
|
.SUFFIXES:
|
|
|
|
### Flags affecting all rules
|
|
|
|
# A GNU make extension since gmake 3.72 (released in late 1994) to
|
|
# remove the target of rules if commands in those rules fail. The
|
|
# default is to only do that if make itself receives a signal. Affects
|
|
# all targets, see:
|
|
#
|
|
# info make --index-search=.DELETE_ON_ERROR
|
|

### Global variables
|
|
|
|
## comma, empty, space: handy variables as these tokens are either
|
|
## special or can be hard to spot among other Makefile syntax.

### Templates
|
|
|
|
## mkdir_p_parent: lazily "mkdir -p" the path needed for a $@
|
|
## file. Uses $(wildcard) to avoid the "mkdir -p" if it's not
|
|
## needed.
|
|
##
|
|
## Is racy, but in a good way; we might redundantly (and safely)
|
|
## "mkdir -p" when running in parallel, but won't need to exhaustively create
|
|
## individual rules for "a" -> "prefix" -> "dir" -> "file" if given a
|
|
## "a/prefix/dir/file". This can instead be inserted at the start of
|
|
## the "a/prefix/dir/file" rule.

|
$(if $(wildcard $(@D)),,$(QUIET_MKDIR_P_PARENT)$(shell mkdir -p $(@D)))
