Thanks Neil, that's a bit odd. Did your previous config.sh, which gets
loaded *after* hostperl and hostgenerate are set, already have empty
values in for hostperl, hostgenerate? Try removing the config.sh first?
This is probably also the reason that your CC value is not being used/set.
I should try and move the actual setting of these until after config.sh is
loaded.
I also notice you have an extra "linux" in your Configure options:
LINE="-des -Dusedevel -Dusecrosscompile "
LINE=" ${LINE} -Dcc=arm-linux-gnueabi-gcc linux" <---
LINE=" ${LINE} -Dtargetarch=armel -Dtargethost=\"armel\""
Which is maybe why the targethost value is ignored, see "No targethost for
running compiler tests against defined, running locally" in the log. Note
that targethost is currently "a remote server/host to run small Configure
tests on" in my branch. I should probably rename it to "buildhost" for
less confusion.
Let me know if you get time to poke it further,
Jess
