OK, yes these c runtime startup files, not have the .ident label like
from glibc.

But the .ident from object file generated by source file is independent
from these c runtime startup files. These files are used at linker time. :s

Maybe in some part of the Makefile "-fno-ident" gcc flags is used ?

$ x86_64-unknown-linux-uclibc-gcc -c hola.c
$ strings -a hola.o | grep GCC
GCC: (GNU) 4.4.0 20090526 (prerelease)
