freebsd-dev/gnu/lib/libstdc++
Dimitry Andric 130515293b When one attempts to compile the tree with -march=i386, which also used
to be gcc's default before r198344, calls to atomic builtins will not be
expanded inline.  Instead, they will be generated as calls to external
functions (e.g. __sync_fetch_and_add_N), leading to linking errors later
on.

Put in a seatbelt that disables use of atomic builtins in libstdc++ and
llvm, when tuning specifically for the real i386 CPU.  This does not
protect against all possible issues, but it is better than nothing.
