Hello;
I want to test some pending changes compiling on an x86_64 build host, but am
having some problems on a new Ubuntu 18.04 host. It has GCC7 by default so I
installed packages "gcc-5" / "g++-5" and tried again. After setting...
```
export CC=gcc-5
export HAIKU_CC_x86_64=gcc-5
```
...the configure phase works out well, but then it seems to have some problems
in "HaikuConfig.h:60". I guess "__x86_64__" is not being set. I dug around
and saw a few places where "__x86_64__" might be set, but thought I'd check
here first in case anybody else has any advice.
Regards;
