Are you crosscompiling?

> Are you crosscompiling?

I first encountered the bug on cross-compiling. Then I recompiled glibc directly on the target system, and the same thing happened.

Attached patch fixes this both for cross- and non-cross.

Can you past the buildlog?

[Comment 6 SpanKY 2010-09-30 00:03:25 UTC]

patch looks good to me.  added to 2.11.2 and 2.12.1 patchsets.  thanks !

[Comment 7 SpanKY 2012-08-12 06:22:21 UTC]

btw, this patch isn't entirely correct, but i don't have the energy to fix it up.  if someone feels like it, please read the referenced thread and post an update.

and it's merged into mainline finally :)
