[Buildroot] [git commit] dhcpcd: needs MMU

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=55227475957af0a6a9d1377bc9e2e6103febedba
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
