This commit adds support for the Atmel AVR 8-bit RISC architecture. This is the first 8-bit architecture to be added to crosstool-ng so the configuration options for 8-bit architectures are added here as well. gcc has had support for AVR for quite a while, at least since the 4.3 series for the currently popular ATmega microcontroler series. The AVR architecture only supports bare-metal toolchains. gcc for the AVR 8-bit architecture, usually referred to as avr-gcc, is commonly used in conjunction with the avr-libc library which provides additional resources for the Atmel AVR 8-bit microcontrollers. avr-gcc can also be found as a supported package in some recent Linux distributions. This commit also closes #66 Signed-off-by: Erico Nunes <nunes.erico@gmail.com>

If you have some pre-installed kernel headers lying around, you can
|
|
enter the path to these headers, below, they will be copied from
|
|
there, and into the toolchain's sysroot.

Note:
|

This will *not* let you use a complete kernel tree!

If you want to use your own full kernel tree, then you want to say 'N'

If you say 'n' here, the path above is expected to point to a directory
|
|
containing readily prepared headers
|
|
|
|
If you say 'y' here, then the path above is expected to point to a
|
|
tarball of such a directory.
|
|
|
|
Eg., if your headers are available in: /foo/bar/buz/my_hdrs/include,
|
|
say 'n' here, and enter: /foo/bar/buz/my_hdrs below.
|
|
|
|
Now, passing a tarball around is easier than passing a directory, so
|
|
if you want to, you can make a tarball of /foo/bar/buz/my_hdrs/include,
|
|
say 'y' here, and enter the path to this tarball below.
