Now that we do not target BeOS and also do not include the main headers
directory when building "build" binaries, we can drop the separate
config_build directory and thus also the separate BeBuild.h, and just
..-include the regular one.
The build BeBuild.h defined empty _IMPEXP_ROOT and _IMPEXP_BE preprocessor
macros that the regular one does not; so I also re-synchronized
headers which used these as needed.
That's just leading to problems.
* Fixed various 64 bit warnings when building libbe_build.so. One of the more
serious issues, that might bite us, is that 64 bit Linux defines dev_t to
unsigned long, while Haiku code assumes that it is signed and 32 bit. We'll
see...
