When cross compiling inteltool with musl-libc the <sys/io.h> header is not included due to this test in inteltool.h:

Same story on other platforms: sys/io.h[1] is implemented through i386_iopl(2)[2]/amd64_iopl(2)[3] and sysarch(2)[4] on OpenBSD.
Many tools under util/ are developed with Linux/glibc in mind (only).
Unfortunately I'm not sure what the right test is here, since the musl libc team is opposed to having a __MUSL__ define:
