[CMake] OS/390 patches

[Magnus Sirwiö]

Hi,

Find attached patches to get most of CMake functionality on OS/390 
mainframes.

Note 1
The curl part is not yet working.

Note 2
For some reason I had to patch away the MVS remapping of long external 
names. Long names work fine for me in USS - Unix System Services.

Note 3
The patch is against CMake 2.4.3

- Magnus
