Both solutions, you suggest, fail.

The first, "START_FILES='pre-crt0.o'", with

[...]
sysdep.o: In function `start_of_text':
/tmp/emacs/src/sysdep.c:1534: undefined reference to `__start'
collect2: ld returned 1 exit status
make[2]: *** [temacs.exe] Error 1
make[2]: Leaving directory `/tmp/emacs/build/src'
make[1]: *** [src] Error 2
make[1]: Leaving directory `/tmp/emacs/build'
make: *** [bootstrap] Error 2

and the second, "START_FILES=", with:

[...]
sysdep.o: In function `start_of_text':
/tmp/emacs/src/sysdep.c:1534: undefined reference to `__start'
sysdep.o: In function `start_of_data':
/tmp/emacs/src/sysdep.c:1586: undefined reference to `_data_start'
collect2: ld returned 1 exit status
make[2]: *** [temacs.exe] Error 1
make[2]: Leaving directory `/tmp/emacs/build/src'
make[1]: *** [src] Error 2
make[1]: Leaving directory `/tmp/emacs/build'
make: *** [bootstrap] Error 2

Ciao,
