on glibc, this header is getting pulled in automatically via

According to the Linux man-page SYSCALL(2), syscall
is declared in unistd.h. On my Debian Linux with glibc,
this information is correct. Here is the result of grep:
/usr/include/unistd.h:extern long int syscall (long int __sysno, ...)
__THROW;
unistd.h is included implicitly via qemu-common.h,
so if you don't get the declaration, there is a buggy
implementation of the header files in musl:
http://git.musl-libc.org/cgit/musl/plain/include/unistd.h
does not match the Linux documentation.
Please report this to the musl developers.
