[PATCH] Enforce gcc-2.95 as the minimum compiler requirement
Now that sparc64 is using gcc-3.x we can disallow gcc-2.91, etc.
Documentation/Changes already says 2.95.3, which is working fine for me.
With this change, we no longer require that per-cpu data definitions be
initialised. That was a workaround for a bug in older gccs. So remove the
build infrastructure which was checking for that.
Also, mention that nfs-utils-1.0.3 is required. It isn't required yet, but
will be once we enable larger dev_t: there is an interface for exportfs which
passes dev_t's into the kernel which breaks with larger dev_t. That
interface is old, deprecated and is not used in nfs-utils-1.0.3.
