makesyscalls.sh off_t padding check problem for compat linux

[Nicolas Joly <njoly%pasteur.fr@localhost>]

Hi,

For quite some tine now, comat linux syscalls files cannot be
generated anymore (at least for some ports). The problem comes from
makesyscalls.sh off_t paddind check ...

Some compat linux syscalls currently use off_t arguments, but does not
have any padding ... this makesyscalls.sh fails its job.

     int linux_sys_truncate64(const char *path, off_t length);

Don't this check need to be restricted to native syscalls ?
If so how about the attached patch ?
