+Subject: [PATCH] kconfig: use HOSTCC to build the config frontends
+
+Commit 228cb983 ("Simplify build dependencies, shrink Makefile, move more
+config plumbing over to new stuff") replaced $(HOSTCC) with a hardcoded
+"cc" in the rules that build kconfig/conf and kconfig/mconf.
+
+These are build-host programs, so they have to be compiled with the host
+compiler the build system provides. When cross compiling in an
+environment that only exports an explicit HOSTCC (and has no "cc" in
+PATH), "make oldconfig" fails with:
+
+ cc -o kconfig/conf kconfig/conf.c kconfig/zconf.tab.c ...
+ make: cc: No such file or directory
+ make: *** [kconfig/Makefile:43: kconfig/conf] Error 127
+
+The top level Makefile already exports HOSTCC, and scripts/portability.sh
+uses $HOSTCC for the other host-side helpers, so honour it here too.

Upstream reworked the build plumbing in this release: most of the kconfig machinery moved out of kconfig/Makefile into scripts/genconfig.sh and scripts/kconfig.c, and the defconfig/allyesconfig/allnoconfig/randconfig targets are now thin wrappers around genconfig.sh. As part of that cleanup (commit 228cb983) the rules that build the host-side kconfig frontends lost their $(HOSTCC) and were hardcoded to "cc", which breaks cross builds where only an explicit HOSTCC is exported and no "cc" is on PATH. Add a patch restoring $(HOSTCC) there; the rest of the recipe needs no changes.
