The startup code from libgcc never sets @code{EIND}.
Notice that startup code is a blend of code from libgcc and AVR-Libc.
For the impact of AVR-Libc on @code{EIND}, see the
@w{@uref{http://nongnu.org/avr-libc/user-manual,AVR-Libc user manual}}.

It is legitimate for user-specific startup code to set up @code{EIND}
early, for example by means of initialization code located in
section @code{.init3}. Such code runs prior to general startup code
that initializes RAM and calls constructors, but after the bit
of startup code from AVR-Libc that sets @code{EIND} to the segment
of startup code from AVR-LibC that sets @code{EIND} to the segment
where the vector table is located.
@example
#include <avr/io.h>
static void
__attribute__ ((section (".init3"), naked, used, no_instrument_function))
__attribute__((section(".init3"),naked,used,no_instrument_function))
init3_set_eind (void)
@{
__asm volatile ("ldi r24, pm_hh8(__trampolines_start)" "\n\t"
"out %i0, r24" :: "n" (&EIND) : "r24", "memory");
__asm volatile ("ldi r24,pm_hh8(__trampolines_start)\n\t"
"out %i0,r24" :: "n" (&EIND) : "r24","memory");
