binutils and l option of ARFLAGS

[Frédéric Fauberteau <triaxx%NetBSD.org@localhost>]

According to these references:

  https://gnats.netbsd.org/57565
  
https://github.com/NetBSD/src/commit/5e3d878975b77fde0ec4b4a6fa14dd3a0a31b01d
  
https://github.com/NetBSD/src/commit/0572a20ef7afac4e1c1e69840c5ad4360c883ec0

Could we reasonably consider removing the 'l' option from ARFLAGS in 
pkgsrc for NetBSD to be consistent with base system?
