Subject: [PATCH 02/10] bpf tools: Define LD and RM in Makefile for 'make -R'
Building libbpf with 'make -R' causes error:
$ make -R
Auto-detecting system features:
... libelf: [ on ]
... bpf: [ on ]
CC fixdep.o
LD fixdep-in.o
/bin/sh: -r: command not found
make[2]: *** [fixdep-in.o] Error 127
make[1]: *** [fixdep-in.o] Error 2
make: *** [fixdep] Error 2
Makefile for libbpf requires $(LD) and $(RM), but in case of 'make -R'
the builtin variables are gone. This patch define default RM and LD so
it won't fail in 'make -R'.
