Fixed do_configure error:
ERROR: User requested feature sdl
configure was not able to find it.
Install SDL devel
The error message from log.do_configure, and if we check config.log, the
error is:
sysroots/x86_64-linux/usr/lib/libXext.so.6: undefined reference to
`_XEatDataWords'
The _XEatDataWords is provided by libX11.so, the dependencies are:
qemu-native -> sdl(from the host) -> libXext.so(maybe host or native) ->
libX11.so (maybe host or native)
For example on Ubuntu 12.04 x86_64, the link route is:
qemu-native's do_configure sdl checking:
/usr/lib/x86_64-linux-gnu/libSDL.so -->
<sysroots>/x86_64-linux/usr/lib/libXext.so.6 -->
/usr/lib/x86_64-linux-gnu/libX11.so
So it is:
host sdl -> sysroot libXext.so.6 -> host X11.so
qemu-native doesn't depend on libxext-native, so the error would happen
if the libx11-native is being rebuilding and the host's libX11.so
doesn't have _XEatDataWords.
Manually reproduce it on Ubuntu 12.04 x86_64:
$ bitbake qemu-native libx11-native libxext-native
$ bitbake qemu-native libx11-native -ccleansstate && bitbake qemu-native
Note, only qemu-native has this problem since libxext depends on libX11,
and SDL would depend on libxext when x11 is enabled.
