# 1. Added -fno-omit-frame-pointer: perf/tcmalloc-profiler use frame pointers by default
# 2. Added -D__const__= : Avoid over-optimizations of TLS variables by GCC>=4.8
# 3. Removed -Werror: Not block compilation for non-vital warnings, especially when the
#    code is tested on newer systems. If the code is used in production, add -Werror back
