With all Linux ABIs using the expected Linux kABI to indicate syscalls errors, the INTERNAL_SYSCALL_DECL is an empty declaration on all ports. This patch removes the 'err' argument on INTERNAL_SYSCALL* macro and remove the INTERNAL_SYSCALL_DECL usage. Checked with a build against all affected ABIs.

1. Under RTLD_PRIVATE_ERRNO, it must not clobber the private errno

|
when another thread holds the dl_load_lock.

2. It is not obliged to detect and report errors at all.

3. It's not really obliged to deliver a single atomic write
|

(though it may be preferable). */
