* Someone with the official spec should fix this and qemu.
|

|
* I made this CONFIG_HOST_xxx dependant because:
|
||
|
|
* - the qemu implementation just pass them to the host OS
|
||
|
|
* - I don't have an official documentation.
|
||
|
|
* - I build NuttX and run qemu on the same host.
|
||
|
|
* I know this is wrong. But it works for me.
