# Mtime granularity problem.
# It was observed that these commands:
# make allnoconfig; sed -i -e '/CONFIG_TRUE/s/.*/CONFIG_TRUE=y/' .config; make
# sometimes produce busybox with "true" applet still disabled.
# This is caused by .config updated by sed having mtime which is still
# equal to (not bigger than) include/autoconf.h's mtime,
# and thus 2nd make does not regenerate include/autoconf.h.
# Waiting for 1 second after non-interactive "make XXXXconfig"
# prevents this from happening.
#
# We'd like to detect whether filesystem we are on has coarse mtimes,
# but can't do it yet, bbox ls hasn't got --full-time.
