configure: Enable use-xattr or use-xattr-ref automatically.

The previous commit only checked that they worked if the user
enabled them, but now they will be enabled automatically if the
underlying filesystem supports them.

The ReadMe.Compiling has been updated accordingly.

Building Haiku
==========================
This is a overview into the process of building HAIKU from source.

after each update just to be on the safe side.
Depending on your goal, there are several different ways to configure Haiku.
You can either call configure from within your Haiku trunk folder. That will
prepare a folder named 'generated', which will contain the compiled objects.
The first way is to call configure from within your Haiku checkout's root. That
will prepare a folder named 'generated', which will contain the compiled objects.
Another option is to manually created one or more `generated.*` folders and run
configure from within them. For example, imagine the following directory setup:
```
buildtools-trunk/
haiku-trunk/
haiku-trunk/generated.x86gcc2
buildtools/
haiku/
haiku/generated.x86gcc2
```
### Configure a GCC 2.95 Hybrid, from a non-Haiku platform
### Configure a GCC 2.95/GCC 5 Hybrid, from a non-Haiku platform
```bash
cd haiku-trunk/generated.x86gcc2
../configure --use-xattr-ref \
cd haiku/generated.x86gcc2
../configure \
--build-cross-tools x86_gcc2 ../../buildtools/ \
--build-cross-tools x86
```
### Configure a GCC 2.95 Hybrid, from Haiku
### Configure an x86_64 (GCC 5) build, from a non-Haiku platform
```
cd haiku-trunk/generated.x86gcc2
cd haiku/generated.x86_64
../configure --build-cross-tools x86_64 ../../buildtools/
```
### Configure a GCC 2.95/GCC 5 Hybrid, from Haiku

For emulated hardware you should build a disk image (see above). How to set up
this image depends on your emulator. If you use QEMU, you can usually just
provide the path to the image as command line argument to the `qemu`
