[Buildroot] [git commit branch/2018.02.x] Makefile: help: BR2_DEFCONFIG for defconfig must be on command line

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=24b78f0de9726d73ef832c3d5b8cf89e410b7395
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.02.x

The help text says that BR2_DEFCONFIG will be used as input, but a
BR2_DEFCONFIG specified in the existing .config file will *not* be
used. So say explicitly that it must be specified on the command line.
Note that both "BR2_DEFCONFIG=... make defconfig" and
"make defconfig BR2_DEFCONFIG=..." will work.

While we're at it, add a semicolon to separate the two statements.

Note that this overflows the help text beyond 80 characters, but that
is already the case in many other lines.
