You want to add the horrible sys_errlist hack just because you'd have to
patch one more package?

Ideally libc would not export a single variable.  Copy relocations are
simply evil and the code generated for accessing exported variables is
in any case bad.

Try to root out the use of sys_errlist.  Convert the bit of code which 
depends unconditionally on it to use strerror or strerror_r.
