>Description:
mksh is the MirBSD version of the public domain korn shell,
which includes patches from the OpenBSD and Debian pdksh
derivates.

As such, it needs a special handling for the braceexpand
mode as well, else MAKEOBJDIR creation in the nbmake wrapper
will fail.

This problem is not limited to MirOS BSD because mksh is
already part of many other operating systems, such as
Arch GNU/Linux, Crux GNU/Linux, Debian GNU/* and Gentoo
GNU/Linux; it's also available for Mac OS X and Darwin,
Free/Net/Open/DragonFly BSD, Solaris, Interix (Microsoft
Services for Unix 3.5) and GNU/Cygwin.

I have attached a suggested patch.
>How-To-Repeat:
* Install mksh (emerge, apt-get or compile the sources
  yourself using mksh/Build.sh)
* Try to cross-build NetBSD:

$ HOST_CC=mgcc ./build.sh -m pmax -O ~/nbsdpmax/obj -T ~/nbsdpmax/tooldir -U -u release

See it fail after less than one minute on an Athlon XP 500.
>Fix:
The first case branch is for modern mksh; the second one
is for older mksh until and including R20.

I haven't tested this on systems such as Solaris /bin/sh
or /usr/xpg4/bin/sh yet, though.
