[uml-devel] [PATCH 1/2] uml: arch/um/scripts/Makefile.rules - remove duplicated code

[Paolo 'Blaisorblade' Giarrusso]

From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

Duplicated code - the patch adding it was probably applied twice without enough
care.

[uml-devel] [PATCH 2/2] uml: fix dynamic linking on some 64-bit distros

[Paolo 'Blaisorblade' Giarrusso]

From: Rob Landley <rob@landley.net>, Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

The current UML build assumes that on x86-64 systems, /lib is a symlink 
to /lib64, but in some distributions (like PLD and CentOS) they are separate 
directories, so the 64 bit library loader isn't found.  This patch 
inserts /lib64 at the start of the rpath on x86-64 UML builds.
