[avr-gcc-list] gcrt1.S variable initialization

one could save about 16 bytes during startup if there is no 
need for initialized variables.
A conditional compile to the gcrt1.S could be inserted
which checks if there is something to copy.

Something like:
#if _etext != _edata
        ldi     ZL, lo8(_etext); load the end of .text segment
should work.

I hope you are not this tight on bits and bytes that you
need this:)
