Emacs bootstrap: 'ignored' errors [trunk]

[Angelo Graziosi <angelo.graziosi@alice.it>]

Just for completeness, the bootstrap log of current trunk (rev.101821) 
shows up the following 'ignored' errors:

[...]
make[1]: Entering directory `/tmp/emacs/Work/doc/emacs'
rm -f *.aux *.log *.toc *.cp *.cps *.fn *.fns *.ky *.kys \
	  *.op *.ops *.pg *.pgs *.tp *.tps *.vr *.vrs

Those errors were absent in the bootstraps of previous revisions.

Ciao,
