platform_bionic/libc/bionic/new.cpp
Peter Collingbourne 9397bdd13f Make our definition of std::nothrow weak.
We can sometimes fail to link a static executable because of
duplicate definitions of std::nothrow in bionic/libc/bionic/new.cpp
and external/libcxx/src/new.cpp. Fix it by making our definition
weak since it doesn't matter which one ends up being chosen.
