Viktor Malik 0c7e6ff75e tools/resolve_btfids: Fix setting HOSTCFLAGS ... commit edd75c8028 upstream. Building BPF selftests with custom HOSTCFLAGS yields an error: # make HOSTCFLAGS="-O2" [...] HOSTCC ./tools/testing/selftests/bpf/tools/build/resolve_btfids/main.o main.c:73:10: fatal error: linux/rbtree.h: No such file or directory 73 | #include <linux/rbtree.h> | ^~~~~~~~~~~~~~~~ The reason is that tools/bpf/resolve_btfids/Makefile passes header include paths by extending HOSTCFLAGS which is overridden by setting HOSTCFLAGS in the make command (because of Makefile rules [1]). This patch fixes the above problem by passing the include paths via `HOSTCFLAGS_resolve_btfids` which is used by tools/build/Build.include and can be combined with overridding HOSTCFLAGS.
