tools/resolve_btfids: Fix build when cross compiling kernel with clang.

commit a298bbab90 upstream.

When cross compiling the kernel with clang, we need to override
CLANG_CROSS_FLAGS when preparing the step libraries.

Prior to commit d1d0963121 ("tools: fix annoying "mkdir -p ..." logs
when building tools in parallel"), MAKEFLAGS would have been set to a
value that wouldn't set a value for CLANG_CROSS_FLAGS, hiding the
fact that we weren't properly overriding it.

Fixes: 56a2df7615 ("tools/resolve_btfids: Compile resolve_btfids as host program")
