[PATCH] tools: bpf: Fix error in 'make -C tools/ bpf_install'

[PATCH] tools: bpf: Fix error in 'make -C tools/ bpf_install'

[Wei Li]

make[2]: *** No rule to make target 'install'.  Stop.
make[1]: *** [Makefile:122: runqslower_install] Error 2
make: *** [Makefile:116: bpf_install] Error 2

There is no rule for target 'install' in tools/bpf/runqslower/Makefile,
and there is no need to install it, so just remove 'runqslower_install'.

Fixes: 9c01546d26d2 ("tools/bpf: Add runqslower tool to tools/bpf")

Applied to bpf tree, thanks.

Technically runqslower could be installed, but it's better to leave
that to libbpf-tools ([0]), which distributes runqslower along other
BPF-based tools.
