[uml-devel] [PATCH 1/7] UML - Re-remove accidentally restored code

[Jeff Dike <jdike@addtoit.com>]

aout-suppress-aout-library-support-if-config_arch_supports_aout.patch
restores some code which had been deleted by
uml-move-um_virt_to_phys.patch and uml-add-virt_to_pte.patch,
presumably due to a botched diff.

This patch gets rid of it again.
