[uClibc] SIGILL on __JCR_LIST__ with uClibc 0.9.26

[Wen Yang]

Hi,

I recently used uClibc 0.9.26 based toolchain to compile OpenSSL for arm
and I kept getting a SIGILL at some __JCR_LIST__.  The SSL used to work
with the uClibc 0.9.20 based toolchain. 

I am stuck :-(( Can anyone help? Thanks!

Here is what I got from the gdb:

Program received signal SIGILL, Illegal instruction.

Thanks a lot!
