Problem with mk/platform/Interix.mk

[Steve O'Hara-Smith <steve%sohara.org@localhost>]

        Hi,

        I can't send_pr this because Interix hasn't got send_pr :(

        In mk/platform/Interix.mk there is currently this line:

ULIMIT_CMD_memorysize?= ulimit -m `ulimit -H -m`

        Unfortunately Interix ulimit doesn't do -m, it does do -v
so I suggest this line as a replacement.

ULIMIT_CMD_memorysize?= ulimit -v `ulimit -H -v`

        Changing it gets me most of the way to building firefox-gtk1, now
if I can just figure out why nsinstall dumps core ...
