Comment 1 for bug 568337

The failure seems to come from trying to build some x86-specific inline asm in src/svgalib.h:

static __inline__ void port_out(int value, int port)
{
    __asm__ volatile ("outb %0,%1"
              ::"a" ((unsigned char) value), "d"((unsigned short) port));
}

static __inline__ void port_outw(int value, int port)
{
    __asm__ volatile ("outw %0,%1"
             ::"a" ((unsigned short) value), "d"((unsigned short) port));
}

static __inline__ void port_outl(int value, int port)
{
    __asm__ volatile ("outl %0,%w1"
             ::"a" ((unsigned int)value), "Nd" ((unsigned short) port));
}
