Import bmake-20180222

From ChangeLog

* VERSION: 20180222
  Merge with NetBSD make, pick up
  o parse.c: avoid calling sysconf for every call to loadfile

* VERSION: 20180218
  Merge with NetBSD make, pick up
  o var.c: Var_Set handle NULL value anytime.

* VERSION: 20180212
  Merge with NetBSD make, pick up
  o parse.c: do not treat .info as warning with -W

* VERSION: 20171207
  Merge with NetBSD make, pick up
  o var.c: Var_Append use Var_Set if var not previously set
    so that VAR_CMD is handled correctly.
    Add a suitable unit-test.

* VERSION: 20171126

* aclocal.m4: use AC_LINK_IFELSE for AC_C___ATTRIBUTE__
  since AC_TRY_COMPILE puts input inside main()
  which upsets modern compilers.

* VERSION: 20171118
  Merge with NetBSD make, pick up
  o var.c: do not append to variable set on command line
    add unit-test to catch this.
