[commit] Syscall number for SYS_reconfig

[Dave Brolley <brolley@redhat.com>]

[-- Attachment #1: Type: text/plain, Size: 351 bytes --]

I've comitted the attached patch.

The syscall number for SYS_reconfig in libgloss/syscall.h is changing, 
since it was not appropriate for it to be zero. However, legacy MeP code 
expects it to be zero.

This patch allows zero to be recognized as SYS_reconfig for MeP as well 
as whatever number has been assigned to it in libgloss/syscall.h.
