A few fixes for cross-building the sefltests out of tree. This will
enable wider automated testing on various Arm hardware.

Changes since v1 [1]:
* Use wildcard in patch 5
* Move the MAKE_DIRS declaration in patch 1

[1] https://lore.kernel.org/bpf/20210112135959.649075-1-jean-philippe@linaro.org/

Jean-Philippe Brucker (5):
  selftests/bpf: Enable cross-building
  selftests/bpf: Fix out-of-tree build
  selftests/bpf: Move generated test files to $(TEST_GEN_FILES)
  selftests/bpf: Fix installation of urandom_read
  selftests/bpf: Install btf_dump test cases

Build bpftool and resolve_btfids using the host toolchain when
cross-compiling, since they are executed during build to generate the
selftests. Add a host build directory in order to build both host and
target version of libbpf. Build host tools using $(HOSTCC) defined in
Makefile.include.

When building out-of-tree, the .skel.h files are generated into the
$(OUTPUT) directory, rather than $(CURDIR). Add $(OUTPUT) to the include
paths.

During an out-of-tree build, attempting to install the $(TEST_FILES)
into the $(OUTPUT) directory fails, because the objects were already
generated into $(OUTPUT):

rsync: [sender] link_stat "tools/testing/selftests/bpf/test_lwt_ip_encap.o" failed: No such file or directory (2)
rsync: [sender] link_stat "tools/testing/selftests/bpf/test_tc_edt.o" failed: No such file or directory (2)

Use $(TEST_GEN_FILES) instead.

For out-of-tree builds, $(TEST_CUSTOM_PROGS) require the $(OUTPUT)
prefix, otherwise the kselftest lib doesn't know how to install them:

The btf_dump test cannot access the original source files for comparison
when running the selftests out of tree, causing several failures:

awk: btf_dump_test_case_syntax.c: No such file or directory
...

Add those files to $(TEST_FILES) to have "make install" pick them up.
