Re: TARGET undefined in bucomm.c

[Luke <hazelnusse@gmail.com>]

The gcc I am using is what came with Kubuntu 11.04:
luke@ThinkPad-W510:binutils$ gcc --version -v
Using built-in specs.

When I run command given by make, but with the -v option as you suggest, I get:

I just did a clean install of Ubuntu 11.04 on a virtual machine and it
compiled just fine out of the box.  My host machine is Kubuntu 11.04
and gcc is the same version and seems to be built with the same flags,
so it would be weird if those two things were the same yet gcc was
somehow to blame.  Maybe something else with my build environment is
messing things up?
