Add CFLAGS and LDFLAGS for each feature to be checked. This allows to pass flags and parameters to the feature checks compilation.
Use the per-feature check flags for the unwinding feature in order to correctly compile the 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 ARMv7 and ARMv8 with 'make DEBUG=1 LIBUNWIND_DIR=/usr/local -C tools/perf'
