[PATCH] ARM: fix ARMv4+Feroceon multiplatform build

[Arnd Bergmann]

The feroceon copypage implementation cannot be built when targetting an
ARMv4 CPU, so we need to pass the march=armv5te flag manually to gcc
when building this file. This is obviously safe since that code will
not be executed on ARMv4.
