someone on irc looked at sparc about half a year ago,
but i don't know how far that got.

git log --stat 01ef3dd9c5fa7a56aa370f244dd08e05c73010f5

shows which files were changed in the aarch64 port,
most of them are mandatory for a port.

endianness is not an issue (there is nothing in musl
that can meaningfully depend on endianness.. except
some linux syscall api structs need endian dependent
paddings, but that's target specific code).

the real issue is that the linux kernel interfaces
for sparc have a lot of gratuitous incompatibilities
with other targets so doing arch/sparc/bits/*.h
is a significant amount of work.
