When the cross-compile part of the configure check was last touched, the commit message said it to be "Temporary fix". Commit date: "Date: Sun Nov 17 19:18:13 2002 +0000"
Making the check cached, and thus supporting cache variable for the user to set, seems to resolve the issue for OpenEmbedded for now.
Should do at least that before 3.0.3 (and even on S2_6).
As already said, meant for S2_6 too.
OpenEmbedded build gives warnings about use of deprecate ftime() in timing.c.
timing.c falls back to using ftime, if gettimeofday() is not available. About detection of gettimeofday() config.log says:
configure:39692: checking for working gettimeofday
configure:39699: result: unknown: cross-compiling
