It looks like the only distro supporting Alpha is Gentoo. I pulled
down the installation media, and everything is ELF except for firmware
COFF files:

$ find . -type f | xargs file | grep -Ei ':.*(out|coff)'
./lib/firmware/meson/vdec/g12a_hevc_mmu.bin: MIPSEB MIPS-III ECOFF executable not stripped - version 0.0
./lib/firmware/meson/vdec/g12a_vp9.bin: MIPSEB MIPS-III ECOFF executable not stripped - version 0.0
./lib/firmware/meson/vdec/gxl_hevc_mmu.bin: MIPSEB MIPS-III ECOFF executable not stripped - version 0.0
./lib/firmware/meson/vdec/gxl_vp9.bin: MIPSEB MIPS-III ECOFF executable not stripped - version 0.0
./lib/firmware/meson/vdec/sm1_hevc_mmu.bin: MIPSEB MIPS-III ECOFF executable not stripped - version 0.0
./lib/firmware/meson/vdec/sm1_vp9_mmu.bin: MIPSEB MIPS-III ECOFF executable not stripped - version 0.0
./lib/firmware/qca/crbtfw32.tlv: mc68k COFF object not stripped

So, since it's an easy revert, sure. Let's do it.
