#70995: pcc fails to build on powerpc: Undefined symbols: "_builtin_frame_address"

 Reporter:  barracuda156  |      Owner:  (none)
     Type:  defect        |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.10.1
 Keywords:  powerpc       |       Port:  pcc
--------------------------+--------------------
 There are two problems:

 1. Configure hardcodes x86_64 arch on 10.6+, which breaks ppc and likely
 i386. Easy to fix:

 However, at the end the build fails on linking for me:
