From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: lz4: fix KERNEL_LZ4 support

The updated lz4 library removed the #ifdef guards around the various
EXPORT_SYMBOL statements in the original kernel lz4 support, which broke
CONFIG_KERNEL_LZ4 on x86:

x86_64-linux-ld: -r and -pie may not be used together
scripts/Makefile.build:308: recipe for target 'arch/x86/boot/compressed/misc.o' failed

This uses a simpler way to do the same thing, by overriding the
EXPORT_SYMBOL macro.
