The recent stable ebuild for apache-tools is failing to compile on my sparc box. The error messages are showing undefined references to various atomics, but adding -latomic to LDFLAGS does not help.

tentatively adding as blocker to bug 721344 but it's not a 32 bit arch...
Sparc userland is usually 32bit for performance, though the kernel is 64. I took a look a the machine again, and I found that apache-tools-2.4.46 is already installed - portage is attempting to re-build it when I run `emerge -uavND @world`. Looking closer, the problem appears to be in dev-libs/apr-1.7.0-r1: libapr-1.so contains undefined references to __sync_fetch* and friends, which breaks anything trying to link against it. Notably, these aren't included in libatomic - that was a red herring. When I build apr-1.6.3-r4 manually, it doesn't exhibit this behavior, but unfortunately emerge won't let me downgrade for some reason.
Created attachment 691857 [details] build.log (2.4.46, ppc) Same on ppc.
