 ideal way to go, but a patch reverting that commit would also work.

 oh, that is nasty... it hampers so many good systems... I tried applying
 the patch you mentioned reverse and compilation fails futher:


 {{{
           Undefined symbols for architecture i386:
             "_clock_gettime", referenced from:
                 std::sys::unix::time::Timespec::now::h30810a3321b633c8
 (.llvm.16531347933994784664) in std-
 0d102736d5b7d56a.std.5eedb8253ab94e49-cgu.12.rcgu.o
           ld: symbol(s) not found for architecture i386

 }}}

 Do we have that in legacy support?
