dev86: don't require dev86-native to build dev86

Instead of installing binaries and patching the makefiles to run external commands, simply
build ifdef using BUILD_CC instead of CC.

This patch is now upstreamable, the recipe is less complicated, and nativesdk works.

-Subject: [PATCH] Makefile: use ifdefg from dev86-native instead of target
-
-* recipe is restricted to:
-  COMPATIBLE_HOST = "(i.86|x86_64).*-linux"
-  so it's less likely to reproduce invalid combination of
-  host and target, but I guess if you have aarch64 build
-  machine and build for x86 then it might fail as for Bruce:
-
-| ./ifdefg -MU  makefile.in >tmp.mak
-| /bin/sh: 1: ./ifdefg: not found
-| make[1]: *** [Makefile:46: make.fil] Error 127
-
-  use ifdefg from native build to increase chances that it
-  will be compatible with your host system
