[PATCH v1 2/6] perf build: Don't always set -funwind-tables and -ggdb3

[Ian Rogers <irogers@google.com>]

Commit 6a40cd90f5de ("perf tools: Add libunwind dependency for DWARF
CFI unwinding") added libunwind support but also -funwind-tables and
-ggdb3 to the standard build. These build flags aren't necessary so
remove, set -g when DEBUG is enabled for the build.
