Would it be possible to get access to this Realtek toolchain? I'd like
to check the behavior, and understand a bit more the issue, because it
looks a bit suspicious/strange.

The sed expression is supposed to replace:




So I don't quite see how the ending "libc" in mips-linux-uclibc can
affect this.

Also, for your next patches, could you send them with the patch
description in the commit log (currently your commit log is just
"IPCSDK-6460", which is not very useful) ? Also, they should be sent
with "git send-email", so that the patch is inline.

Thanks a lot!
