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.
