You could do something like (untested):
There is a problem with OPEN_MAX as well, sys/params.h uses it to define
NOFILE. How to solve that one?

BTW: While reading this, I have noticed only Alpha has code for
_PC_FILESIZEBITS. Shouldn't we just kill Alpha's version of *pathconf.c and
use one common because >2GB files are now supported on all arches?
Or should we check the kernel version first? Note that if we do check
version, we have to do it on alpha/sparc64 as well, though with a different
kernel version number, because it did not work for quite some time.

	* sysdeps/unix/sysv/linux/pathconf.c: Include linux/limits.h before
	limits.h to get LINK_MAX definition.
	* sysdeps/unix/sysv/linux/fpathconf.c: Likewise.
	* sysdeps/unix/sysv/linux/alpha/pathconf.c: Likewise.
	* sysdeps/unix/sysv/linux/alpha/fpathconf.c: Likewise.
