[PATCH v2 01/20] linux-user: introduce parameters to generate syscall_nr.h

[Laurent Vivier]

This will be used when we'll import syscall.tbl from the kernel

Add a script to remove all the dependencies to syscall_nr.h
that point to source directory and not to the build directory.
The list of arch will be update while the generated files are added.
