Fixes http://autobuild.buildroot.net/results/f53/f53d4d47a6b65c40c1b122dfad61d9164e533bf0/ Actually only the linux-user code needs it, but with the _CUSTOM_TARGETS option it is difficult to ensure it only for userland emulation, so just add it to the main qemu option. At the same time add the missing wchar/mmu dependencies to the comment. Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

QEMU is a generic and open source machine emulator and virtualizer.
|
|
|
|
When used as a machine emulator, QEMU can run OSes and programs made
|
|
for one machine (e.g. an ARM board) on a different machine (e.g.
|
|
your own PC). By using dynamic translation, it achieves very good
|
|
performance.
|
|
|
|
When used as a virtualizer, QEMU achieves near native performances
|
|
by executing the guest code directly on the host CPU. QEMU supports
|
|
virtualization when executing under the Xen hypervisor or using the
|
|
KVM kernel module in Linux. When using KVM, QEMU can virtualize x86,
|
|
server and embedded PowerPC, and S390 guests.
