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).

fenv.h provides functions to control the floating point environment,

For some architectures, fenv.h is incomplete, so is not installed

by default. x86 is known to have a rather complete fenv.h, so it is

|
installed by default only for x86.

If you need fenv.h on other architectures, say 'y' here, but you may

encounter some issues.

Depending on where the resulting toolchain will be used, you may need

to tweak the "system" part of the target tuple. Buildroot prefers

to have arm-*-linux-uclibcgnueabi; OpenEmbedded prefers
|

arm-*-linux-uclibceabi. Other tools seem to either accept both, or
|
|
don't care about the suffix.
