I think this must be a musl problem. Quoting the full error

The compiler is complaining because the system headers (provided by
musl) are defining these structs both in asm/sigcontext.h and
in signal.h, which means those headers can't both be included
at once. This isn't QEMU related: musl's headers just seem to
be broken here. glibc doesn't have this bug.
