Another source of stuff is that buildroot has over 30 qemu defconfigs:

buildroot$ ls configs/qemu* | sed 's/.*qemu_\(.*\)_defconfig/\1/' | xargs
aarch64_virt arm_versatile arm_versatile_nommu arm_vexpress m68k_mcf5208
m68k_q800 microblazebe_mmu microblazeel_mmu mips32r2el_malta mips32r2_malta
mips32r6el_malta mips32r6_malta mips64el_malta mips64_malta mips64r6el_malta
mips64r6_malta nios2_10m50 or1k ppc64_e5500 ppc64le_pseries ppc64_pseries
ppc_g3beige ppc_mpc8544ds ppc_virtex_ml507 sh4eb_r2d sh4_r2d sparc64_sun4u
sparc_ss10 x86_64 x86 xtensa_lx60 xtensa_lx60_nommu

With corresponding board/qemu files that have a kernel config and a readme.txt
with the qemu invocation.

Turning that into a comment like:

Still requires a bit of massaging. And I have yet to get buildroot to produce a
portable statically linked host toolchain, let alone target toolchain. But it's
a resource I keep meaning to look at. (And point the musl-libc guys at to go
"hey, here's an emulated reference system you can use to add musl support for
this target...")
