Introduce infrastructure to build the internal Rust library. This mirrors the infrastructure we have added to Meson in the preceding commit. Developers can enable the infrastructure by passing the new `WITH_RUST` build toggle.

### 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
|
|
.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.

|
|
## "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
