Ok, I get it.

I configure with:

  opt='--enable-checking=all --enable-autodepend --enable-dependency-tracking'

I don't check which of this option make Emacs (temacs or how it called during
build) tooooo slow.

I think that this is a '--enable-checking=all' but don't try. Just disable all
of them. Am I right?

>From 'configure':

  --enable-dependency-tracking   do not reject slow dependency extractors

  --enable-checking[=LIST]
                          enable expensive run-time checks. With LIST, enable
                          only specific categories of checks. Categories are:
                          all,yes,no. Flags are: stringbytes, stringoverrun,
                          stringfreelist, xmallocoverrun, conslist, glyphs
