This is what I've found:
In the libstdc++-v3 Makefile CXXFLAGS are set to -O2 -pipe
-march=native -D_GNU_SOURCE. While my actual CXXFLAGS are CXXFLAGS=-O2
-pipe -march=native. But, in this case My CXXFLAGS_FOR_TARGET is set
to "-O2 -pipe -mcpu=v8".
CFLAGS in libstdc++-v3 Makefile is set to my CFLAGS_FOR_TARGET.
Does this give you anything?
