The futility.lds linker script was used to generate a table with all the symbols in a specific section called .futil_cmds listed in order under the symbol "futil_cmds". This allows the source files to define a command and let the linker figure out the list of compiled commands. Nevertheless, passing this linker script makes the linker leave a gap of about 2MiB in the output ELF file. Instead of mess up with linker scripts just to generate a table of commands, this patch generates such table in the Makefile looking at the included sources and compiling that table. The result is a futility binary of about 88 KiB instead of the 2.1 MiB required originally. This patch also adds sys-boot/chromeos-u-boot to the list of ebuilds tested by emerge_test.sh. BUG=chromium:408926 BRANCH=None TEST=BOARD=link ./emerge_test.sh TEST=BOARD=daisy_spring ./emerge_test.sh TEST=`readelf -S futility` shows no gap. TEST=/usr/bin/futility shows no difference in the help output.
