[PATCH v3 03/12] automation: pass --disable-werror for QEMUU builds if libc is musl

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

QEMU upstream builds with warnings when libc is musl:

  #warning redirecting incorrect #include <sys/signal.h> to <signal.h>

Disable -Werror by passing --disable-werror to the QEMUU config script
if libc is musl.
