+Subject: [PATCH] linux: fix passing of host CFLAGS and LDFLAGS
+
+We were passing HOSTCFLAGS="$(HOSTCFLAGS)" to Linux. However:
+
+ - HOSTCFLAGS in Buildroot doesn't exist, and is empty, so this
+   assignment never did anything. The name of the variable in
+   Buildroot in HOST_CFLAGS.
+
+ - HOSTCFLAGS in Linux isn't used everywhere, and passing it overrides
+   the default HOSTCFLAGS value defined in the main Linux kernel
+   Makefile.
+
+In addition, there is no way to pass additional host LDFLAGS in the
+Linux kernel build system.
+
+Therefore, we simply shoehorn our HOST_CFLAGS and HOST_LDFLAGS while
+passing HOSTCC to the Linux kernel build system. This has been tested
+to work fine with host OpenSSL and host libelf only available in
+$(HOST_DIR).
