Hi.

When building the cross_tools target, HOSTCFLAGS and HOSTLDFLAGS will propagate to the target build. This should not happen and is easy to prevent.

In the current U-Boot build system (= Kbuild), CFLAGS is never set, never referenced.
For the target build, KBUILD_CFLAGS is used instead.
So, $(CFLAGS) is always empty unless your environment explicitly sets it. Likewise for LDFLAGS.
Did you mean
HOSTCFLAGS = HOSTLDFLAGS =
or
HOSTCFLAGS = $(KBUILD_CFLAGS) HOSTLDFLAGS =
?
