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

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'

Jean Pihet (2):
  perf: add per-feature check flags
  perf: unwinding: use the per-feature check flags
