HOSTCFLAGS is used when building tools running on your build machine.
Try something like this (untested, whitespace damaged):
diff --git a/scripts/Kbuild.klibc b/scripts/Kbuild.klibc
index f500d535..3e8124f7 100644
--- a/scripts/Kbuild.klibc
+++ b/scripts/Kbuild.klibc
@@ -69,7 +69,7 @@ include $(srctree)/scripts/Kbuild.include
KLIBCREQFLAGS := $(call cc-option, -fno-stack-protector, ) \
$(call cc-option, -fwrapv, )
KLIBCARCHREQFLAGS :=
-KLIBCOPTFLAGS :=
+KLIBCOPTFLAGS := -g
KLIBCWARNFLAGS := -W -Wall -Wno-sign-compare -Wno-unused-parameter
KLIBCSHAREDFLAGS :=
KLIBCBITSIZE :=
If you use make V=1 then you should be able to see the
full gcc command line, where -g should be included with
theabove fix.
