New Revision: 329345
URL: https://svnweb.freebsd.org/changeset/base/329345

Log:
  Eliminate bsd.stand.mk and -fPIC 32-bit intel builds
  
  OK. We don't really need a bsd.stand.mk, and it was causing a -fPIC
  for the toolchain to be added (bogusly) when building on amd64. Pull
  all relevant defs back into defs.mk and delete bsd.stand.mk.
  
  This saves about 15-20k on i386 loader and zfsloader which when
  combined with Lua give us a lot more stack space in those constrained
  environments.
