crossgcc: Fix build with musl libc

Work around an include-order issue when building against musl. When
<sched.h> is included after GCC's "system.h", the build fails because
calloc() is already poisoned by accident:

sched.h:xx:y: error: attempt to use poisoned "calloc"

+Musl's <sched.h> uses calloc() which is marked as poisoned by GCC's
+"system.h". Work around that by making sure that <sched.h> gets
+included first.
