[libvirt] [PATCH 3/3] build: storage: Macro 'MKFS' is undefined on some platforms.

[Peter Krempa]

Mac OS X 10.6. Snow Leopard and probably other do not provide a mkfs
command to create filesystems. Macro MKFS then remained undefined and
did not provide any substitute, so that build failed on a missing
argument.
