Switch gen-kconfig to new framework
Also: - Move companion_* to comp_* to match the kconfig symbols - Replace bootstrap with former gen-versions.sh - Fold *.in.2 into their respective first parts; this moves common options to the end - if it is undesirable, inclusion of *.in can be moved where *.in.2 used to be (but that will also move version selection after common options). - Retire addToolVersion.sh (may later replace with a more comprehensive script that tries to download the added tarballs, copy the patches and try to apply them, and create a version.desc).

Is you say 'y' here, then the tuple for the toolchain will end

up with *eabihf, instead of the usual *eabi.
|

|
|

|
*eabihf is used to denote that the toolchain *is* using the
|
||||||
|
hard-float ABI, while *eabi is just an indication of using the
|
||||||

soft-float ABI.
|
||||||
|
|
||||||
|
Ie. all one can say is: *eabihf ⊢ hard-float ABI
|
||||||
|
|
||||||
|
Saying 'n' here does *not* impact the ability of the toolchain to
|
||||||
|
generate hard-float instructions with the hard-float ABI. It is a
|
||||||
|
purely cosmetic thing, used by distros to differentiate their
|
||||||
|
hard-float-ABI-using ports from their soft-float-ABI-using ports.
|
||||||
|
(eg. Debian Wheezy and above).
|
||||||
|
|
||||||
|
This is an option, as not all versions of gcc/binutils do support
|

such tuple, and fail to build with *eabihf. Stock gcc version up
|

to, and including 4.7.2 have an issue or another with *eabihf.

This option is here for the future.
