I am not sure this is a good idea. Looking at it this indeed seems to be
correct. Anyway, at least in the Linux kernel I can find things like:
codesize = (unsigned long)_etext - (unsigned long)_text;
If we have _etext = . the above results in the correct codesize, but if
we change this to _etext = . - 1 we would have to do
codesize = (unsigned long)_etext - (unsigned long)_text + 1;
instead.
Everyone else including the kernel and the standard linker scripts from
ld have _etext = .; so I vote for keeping it that way.
