Buggy configure checks in the 4.1 branch

[Francois Tigeot]

Hi,

I've just been bitten by buggy configure checks which assume the presence
of the non-standard "tac" utility.

They are present at the very least in m4/ax_boost_system.m4 and the liborcus
bundled library.

The issue has already been reported to the autoconf people and applied to
their devel branch. The discussion is visible here (with patch):

Should I fill a bug report ?
