Various build failures, I'm afraid:

x86-64/Linux/gcc:

configure produces an error message:

ERROR: ASAN build enabled, but ASAN header is too old.
       Without code annotation, the report may be inferior.

even though this configure did not explicitly request ASAN.
Then configure seems to exit successfully anyway, since the
build proceeds.

For some reason the build creates config-target.h a lot:

make: Leaving directory '/home/petmay01/linaro/qemu-for-merges/build/alldbg'
  GEN     config-target.h
  GEN     config-target.h

  GEN     qapi-event.h
[etc]

Then it runs configure again, this time without the ERROR message,
and eventually fails with:

  CC      hw/display/exynos4210_fimd.o
/home/petmay01/linaro/qemu-for-merges/hw/display/exynos4210_fimd.c: In

error: case label does not reduce to an integer constant
     case FIMD_WINCON_BUF2_STAT:
     ^

On sparc64 host configure fails:

config-host.mak is out-of-date, running configure

ERROR: configure test passed without -Werror but failed with -Werror.
       This is probably a bug in the configure script. The failing command
       will be at the bottom of config.log.
       You can run configure with --disable-werror to bypass this check.

The bottom of config.log is:
