Subject: um: Build always with -mcmodel=large on 64bit
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fff6540cbcb56a6ae92d4fd4b0864c8d13a8f932;p=linux-beck.git

um: Build always with -mcmodel=large on 64bit

On UML SUBARCH can be x86, x86_64 and i386 and if it is x86
we use uname -m to select a defconfig.
Therefore we can no longer use -mcmodel=large only if SUBARCH
is x86_64.
