tools/resolve_btfids: Fix build when cross compiling kernel with clang.
commit a298bbab903e3fb4cbe16d36d6195e68fad1b776 upstream.
When cross compiling the kernel with clang, we need to override
CLANG_CROSS_FLAGS when preparing the step libraries.
Prior to commit d1d096312176 ("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: 56a2df7615fa ("tools/resolve_btfids: Compile resolve_btfids as host program")
