Subject: tools/lib/lockdep: Fix link creation warning
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=013e379a3094ff2898f8d33cfbff1573d471ee14;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

tools/lib/lockdep: Fix link creation warning

This warning triggers if the .so library has already been linked:

 triton:~/tip/tools/lib/lockdep> make
  CC       common.o
  CC       lockdep.o
  CC       rbtree.o
  LD       liblockdep-in.o
  LD       liblockdep.a
  ln: failed to create symbolic link ‘liblockdep.so’: File exists
  LD       liblockdep.so.4.5.0-rc6

Overwrite the link.
