[libXi] latest GIT fails to build

[Tobias Jakobi]

Interesting bits from compile log:
make[2]: Leaving directory `/root/libXi/src'
make[1]: Leaving directory `/root/libXi/src'
Making all in man
make[1]: Entering directory `/root/libXi/man'
make[1]: *** No rule to make target `XAllowDeviceEvents.3', needed by 
`all-am'.  Stop.
make[1]: Leaving directory `/root/libXi/man'
make: *** [all-recursive] Error 1

I'm currently "hotfixing" this by removing anything from XI_manpages = 
in Makefile.am in man.

Greets,
Tobias
