Confused by building process of newlib

[Amir Bukhari]

I have succuffly cross compiled newlib for powerpc-eabi, but what make me
confused is the following:

There is a number of subdirs like 'nof' 'und' .. Secondly I see during
building that gcc option '-meabi' is overriden by '-mno-eabi'. Both are
parameter to gcc but -mno-eabi is the last one.
My system depend on EABI alot, specialy in interrupt handler, because I use
ucos-ii.
