Jeffery To 236da17e6a rust: Use make's jobserver when building packages ... This allows cargo to use make's jobserver when building packages, by marking the cargo command as recursive (with the + prefix[1]) and setting MAKEFLAGS. This also: * Give cargo/x.py the build directory instead of having to change the current directory (and opening subshells) * Set PKG_BUILD_PARALLEL/HOST_BUILD_PARALLEL for Rust packages to enable the use of make's jobserver [1]: https://www.gnu.org/software/make/manual/html_node/POSIX-Jobserver.html Signed-off-by: Jeffery To <jeffery.to@gmail.com> (cherry picked from commit 0dfc1b508d) [omit changes to arp-whisper and procs] Signed-off-by: Jeffery To <jeffery.to@gmail.com>		2023-10-12 14:02:35 +08:00
