Add CFLAGS and LDFLAGS for each feature to be checked during the build. This allows to pass particular flags and parameters to the feature checks compilation.
Use the per-feature check flags for the unwinding feature in order to correctly compile the test-all, libunwind and libunwind-debug-frame feature checks.
This change set simplifies the flags passing mechanism between the Makefiles in config/Makefile and config/feature-checks; this could be farther optimized by moving the compilation flags to the per-feature check flags for all features to be checked.
Tested on x86_64, ARMv7 and ARMv8 with and without LIBUNWIND_DIR set in 'make -C tools/perf'
