From e5fe12ebb41f4e24340c8c543231095482b6a9d8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] qboot: Disable LTO for ELF binary build step
If LTO is enabled by default qboot fails to link as it exposes
a few issues that break the build:
../code16.c: Assembler messages:
../code16.c:37: Error: redundant addr32 prefix
../code16.c:27: Error: redundant addr32 prefix
../code16.c:18: Error: redundant addr32 prefix
Until fixed suppress this behavior by adding -fno-lto to the end
of the linker flags.
Fixes: #31
