* sysdeps/unix/sysv/linux/fpathconf.c (LINUX_LINK_MAX): Move macro ...
	* sysdeps/unix/sysv/linux/linux_fsinfo.h (LINUX_LINK_MAX): ... here.
	* sysdeps/unix/sysv/linux/pathconf.h: New file.
	(statfs_link_max): New function, guts from fpathconf.c.
	* sysdeps/unix/sysv/linux/fpathconf.c: Rewritten using that.
	* sysdeps/unix/sysv/linux/pathconf.c (__pathconf): Likewise.
	* sysdeps/unix/sysv/linux/alpha/pathconf.c (__pathconf): Rewritten
	to use the linux/pathconf.c code by #include rather than duplication.
	* sysdeps/unix/sysv/linux/alpha/fpathconf.c (__pathconf): Likewise.
