Any ideas? > if you open the original sources (without eautoreconf), and go inside omalloc folder, you'll find the cause in line 120 of configure.ac and/or 12977 of configure. It's hardcoded there that the script should fail if $ac_cv_prog_AR is not "ar". Here, portage already passes (even without your tc-exports etc.) the correct environment to singular's build system but "x86_64-pc-linux-gnu-ar" is not "ar". You could remove that check at all but I'm not a toolchain expert and don't know why the check is there in first place. On my box ar just links to x86_64-pc-linux-gnu-ar so no big deal.
