Subject: [PATCH] build(make): silence nohup output in projppu checksums
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The async checksum lines used `nohup bash -c "...>file..." 2>&1 &`, so nohup's own
stdout was a tty and it printed `nohup: ignoring input / appending to nohup.out`
into the build log. Redirect nohup's output with the $(QEND) macro (>/dev/null 2>&1
in normal builds, empty under VERBOSE), matching the cgroups-v1 cleanup. The
`nohup md5sum < IN > OUT 2>&1` lines are left as-is — they already redirect nohup's
stdout to the checksum file, and $(QEND) would clobber it.
