Subject: [PATCH 33/34] perf tools: Add per-feature check flags

From: Jean Pihet <jean.pihet@...aro.org>

Add CFLAGS and LDFLAGS for each feature to be checked. This allows
to pass flags and parameters to the feature checks compilation.
Also simplifies the feature check makefile, to come in a subsequent patch.
