Thomas, All,

On 2013-11-02 14:47 +0100, Thomas Petazzoni spake thusly:
> dhcpcd fails to build on non-MMU platforms, even with the
> --disable-fork option:
> 
>   bind.o: In function `_daemonise':
>   bind.c:(.text+0x62): undefined reference to `_fork'
>   collect2: ld returned 1 exit status
> 
> Therefore, we make dhcpcd depend on MMU support, and remove the
> non-MMU condition in the .mk file. More recent versions of dhcpcd do
> support non-MMU properly, but this commit intends to be only a fix.
