Pedro is correct that the order isn't quite right and that the sys
objects should be added at the end.
The resolution isn't "link resolution". Libc is built manually in
libc/Makefile.am by traversing the SUBLIB list and using ar to
deconstruct each SUBLIB into its .o files which it places in a temporary
directory. Once complete, it then rebuilds the library from all the .o
files in the temporary directory. The last library to add its .o files
For linux, newlib gets the shared libc library right because it uses
special awk files to build the library and the last 3 set of objects
I will fix this.

Yes, that's what I meant.
Thanks, it works now.
