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

such as rounding mode, exceptions...
|

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.
