* 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.
