   4 Subject: [PATCH] tc: fix xtables incorrect usage of LDFLAGS
   5
   6 The incorrect setting of LDFLAGS causes error below:
   7
   8 > em_ipt.o: In function `em_ipt_print_epot':
   9 > em_ipt.c:(.text.em_ipt_print_epot+0x2e): undefined reference to
  10 > `xtables_init_all'
  11
  12 em_ipt.c gets involved when TC_CONFIG_XT=y, which requires xtables,
  13 while tc/Makefile doesn't pass flags correctly. It adds '-lxtables'
  14 to LDFLAGS instead of LDLIBS.

  16 Fixes: dd296215 ("tc: add em_ipt ematch for calling xtables matches from tc matching context")
