Subject: automake: Remove delays in configure scripts using automake
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=28fa3044d5e978de5801cf9fa02ae596e9ebc833;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

automake: Remove delays in configure scripts using automake

By default automake puts "sleep 1" into the start of configure scripts
which adds pointless delays to them. Rather than do this, lets just assume
our systems are sane.

Since this means our patches touch m4 files, we need to stop automake running
autoreconf so we tweak the do_configure to avoid this.
