- Subject: (toplevel patch) simplify configure
The variables CC_FOR_TARGET, CXX_FOR_TARGET, GCJ_FOR_TARGET were substituted
in 'configure' if Canadian, and in configure.in otherwise. They are now
substituted in 'configure.in' always. (Their values do not change.) Tested
with some combinations of host & target on i686-pc-linux-gnu.
This might conceivably make it harder to do Canadian cross builds targeting
v810, which sets CC_FOR_TARGET in its target Makefile fragment. :-/ If
anyone cares, I'll try to work up some sort of fix.
* configure: Remove unneeded 'export's. Make CC_FOR_TARGET,
CXX_FOR_TARGET, GCJ_FOR_TARGET substituted in configure.in only.
