Fix errno on Alpha

[Daniel Jacobowitz]

Right now, Alpha uses a !samegp optimized branch to call
__errno_location.  This tells the linker that we always want the copy
of __errno_location in this shared object; so syscalls never find the
copy in libpthread.so, and set the main thread's errno instead of the
current thread's errno.  Easily fixed, like so; please apply.

	* sysdeps/unix/alpha/sysdep.S (__syscall_error): Don't use
	!samegp to call __errno_location.
