selftests/bpf: Add BPF_STRICT_BUILD toggle
Distro kernels often lack BTF types or kernel features required by some BPF
selftests, causing the build to abort on the first failure and preventing
the remaining tests from running.
Add BPF_STRICT_BUILD (default 1) to control build failure tolerance. When
set to 0, the PERMISSIVE make variable is assigned a non-empty value that
subsequent Makefile rules use to make individual build steps non-fatal.
When set to 1 (the default), the build fails on any error, preserving the
existing behavior for CI and direct builds.
Users can opt in to permissive mode on the command line:
make -C tools/testing/selftests \
TARGETS=bpf SKIP_TARGETS= BPF_STRICT_BUILD=0
