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 ...
