[PATCH] Fix sysdeps/unix/sysv/linux/alpha/sysdep.h for GCC 3.2

[Jakub Jelinek]

Hi!

GCC 3.2 doesn't like asm ("" : "=" "r" (something)); (while GCC 3.3+ does).
The following patch fixes this by putting = into the constraint.
The linuxthreads Makefile is something I needed to make libpthread.so to
build on Alpha.

2003-01-06  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/alpha/sysdep.h
	(inline_syscall_r0_constraint): Rename to...
	(inline_syscall_r0_out_constraint): ... this.  Add =.
	(inline_syscall[0-6]): Use inline_syscall_r0_out_constraint
	instead of "=" inline_syscall_r0_constraint.
linuxthreads/
	* sysdeps/unix/sysv/linux/alpha/Makefile: New file.
