abslibre/libre/syslinux/0017-single-load-segment.patch

From: Lukas Schwaighofer <lukas@schwaighofer.name>
Date: Sat, 18 Aug 2018 16:56:35 +0200
Subject: Force the linker to put all sections into a single PT_LOAD segment

This is required when using binutils >= 2.31 which writes two PT_LOAD segments
by default. This is not supported by the wrapper.c script used to convert the
shared object into an elf binary.
