[patch] newlib long long printf for rtems

[Nick Clifton]

Hi Aaron,

: this trivial patch adds support for long long (%lld) formatting to 
: newlib's printf and friends when configured for RTEMS.  I do not have
: commit priviliges, so somebody will have to check this in for me.

Are you sure that this is a good idea for all RTEMS targeted systems ?
It does increase the code size which may not be wanted on some
systems.

Cheers
	Nick
