+hwaccess: sys/io.h is not specific to glibc
+
+Under Linux, sys/io.h provides inb and outb, so we really need it.
+However, its inclusion is conditional to the _GLIBC_ define. This is
+usually OK under Linux, since both glibc and uClibc define it (uclibc
+fakes being glibc).
+
+But the musl C library does not impersonate glibc, so we're missing
+including sys/io.h in this case.
+
+Change the include from checking _GLIBC_ to checking whether this is
+Linux, looking for the __linux__ define.
