Subject[PATCH v4] selftests: Fix seccomp to support relocatable build (O=objdir)
Date
Fix seccomp relocatable builds. This is a simple fix to use the
right lib.mk variable TEST_GEN_PROGS. Local header dependency
is addressed in a change to lib.mk as a framework change that
enforces the dependency without requiring changes to individual
tests.

The following use-cases work with this change:

In seccomp directory:
make all and make clean

From top level from main Makefile:
make kselftest-install O=objdir ARCH=arm64 HOSTCC=gcc \
CROSS_COMPILE=aarch64-linux-gnu- TARGETS=seccomp

Changes since v3:
Simplified logic based on comments from Kees and Michael
