Comment (by hgolden):

 I suspect that the problem is caused by the error message being in a
 different language. I wonder if it is possible to add code to the patch to
 change the locale momentarily while in AddDLL and revert it before
 returning? If this can be done, then the error message would be in the
 language we are expecting and the result should be to look for the true
 shared library by scanning the linker script. Of course, this assumes that
 the linker script is still in English. (I don't know if this is the case.)

 If the linker script is in a different language, then the problem becomes
 much harder to solve without identifying the language and selecting the
 appropriate strings to use in the regular expressions.

 Jinhui, please attach the text of /usr/lib/libc.so on your test system so
 we can see what language it is in. Thanks.
