[PATCH v4 0/2] perf: config: add per-feature check flags

[Jean Pihet]

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'
