From the uClibc config option help:

The new version has not been tested much, and lacks ports for arches
|
|
which glibc does not support (like frv, etc...), but is based on
|
|
the latest code from glibc, so it may be the only choice for the

newer ports (like alpha/amd64/64bit arches and hppa).

If you see issues with using pre-generated locales data,

you can try switching this off.

If so, please report the issue, so we can default this
|
|
to off if too many people complain.

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.
