--- Comment #51 from boger at us dot ibm.com ---
Here is the change I made to go-callers.c. This patch along with my previous
changes to extern.go and pprof.go allows the test identified in this issue to
report the correct line number on ppc64le. I wanted to post it here for
comments before I do the bootstrap build and test on ppc64 and ppc64le in case
there is a concern with using an #if defined. This is in libgo/runtime and I
didn't see any other examples where it used the GOARCH value in C code so that
is why I did it this way.
