The underlying issue is that ld64 will always pick a .dylib over a .a when both are available. So pointing at the libstdc++ .libs dir isn't enough - we'll still link with the dylib. AFAIK the only solution available is to mention the full path to the static lib on the command line. Since clang does not do this for us (no -static-libstdc++) we'd have to cook up our own and drive it from some config that determines we are bootstrapping with clang. [That might be a useful variable to have anyway]

Even with that patch, there remains the "silent" issue of not linking statically when clang is the system compiler.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64023 --- Comment #2 from Iain Sandoe --- as commented in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63773 c#14..17 this is caused by $(HOST_EXPORTS) being used at stage#N>1 instead of $(POSTSTAGE1_HOST_EXPORTS) Thus the config test for the bootstrap compiler is affecting the later build. In this case, GCC fails to build because it supports -static-libstdc++ (and thus the option is passed to the build) but it then needs the -B options to allow for spec substitution to work for libstdc++. These are not present in HOST_EXPORTS because, obviously, the host compiler is installed and doesn't need them. NOTE: (clang succeeds because it does not support -staticlibstdc++, so that option is not passed to the stage#3 libs build. However in that case the fault is potentially more subtle, because the library is then being linked with a dependency on the *system* libstdc++.dylib and not the current build.
