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'.
