Re: undefined sbrk in libnosys

[Jeff Johnston <jjohnstn at redhat dot com>]

A change was made last April that removed the headers in sbrk.c.  These headers 
are needed to rename the _xxxx syscalls for systems that define the 
MISSING_SYSCALLS flag.  The powerpc-eabi is one of these platforms.  I have just 
checked the following patch in which fixes the problem.

        * libnosys/sbrk.c: Add include of <_syslist.h> and "config.h".
