The set of changes addresses "Diagnose "make is too old" in configure
(or in the makefile?)" from https://wiki.qemu.org/Features/Meson#Easy.
It also provides cleaner backwards compatible build invocation on macOS.

Changes since v1:
 - Added explicit error for partially-completed configure (Eric B.)
 - Added an empty rule for config-host.mak to avoid second call of
   recursive make (which happened because of implicit force rule)

Roman Bolshakov (4):
  configure: Use discovered make for in-source build
  Makefile: Require GNU make 3.82+
  configure: Prefer gmake on darwin
  configure: Test if $make actually exists

 Makefile  |  5 +++++
 configure | 36 ++++++++++++++++++++++++++++++++++++
