Do you also see this compile failure on git master, or is
it only a problem on the stable branch?

Note that there are two different possible paths here:
 * if configure finds you have iasl it will build the
   q35-acpi-dsdt.hex files from the dsl source files
 * otherwise, we just copy hw/i386/q35-acpi-dsdt.hex.generated
   into the build tree as the .hex file
(at least, this is how master is doing it.)

Some things that might be useful for debugging:
 * if you add "V=1" to your make command line it will print the
   full commands being run rather than the pretty "IASL/CPP/CC"
   short progress info
 * you could look at whether the .hex file you've generated
   matches the .hex.generated file we ship at all

My guess is that your system has a busted iasl of some kind,
in which case you can work around this by passing '--iasl=none'
to configure, but it would be good to identify what's actually
going wrong here.
