[Buildroot] [for-next] configs: select uclibc when needed

[Romain Naour]

Following the switch to Glibc as the default libc in Buildroot [1],
all defconfigs expecting uClibc with wchar (or any other uClibc
specific option) must now select BR2_TOOLCHAIN_BUILDROOT_UCLIBC too.

Some defconfigs provided by Buildroot select BR2_TOOLCHAIN_BUILDROOT_WCHAR
without selecting BR2_TOOLCHAIN_BUILDROOT_UCLIBC.

Fixes:
https://gitlab.com/kubu93/buildroot/-/jobs/2911738579

This also break all defconfig fragments from
support/config-fragments/autobuild, but they are now deprecated
following utils/genrandconfig --no-toolchains-csv option:

I think we should rather switch those defconfigs to use the new
default, i.e glibc.

Best regards,

I'm agree on the principle to switch them to glibc but boards defconfig where
only runtime tested with uclibc. Also we may need to increase the file system
image (BR2_TARGET_ROOTFS_EXT2_SIZE) when needed.That's why I choose to keep
uclibc in this patch.

But all other defconfig switched already to glibc... maybe
BR2_TARGET_ROOTFS_EXT2_SIZE=60M is now too small for some case?

Best regards,
Romain

True, but I don't have much doubt that glibc will work fine if uclibc
was working fine. We're anyway already updating the versions of
gcc/binutils/uclibc for all defconfigs without necessarily checking
again on hardware.

The size issue is not an issue: we will get a hard build failure if we
reach the maximum size, so it's easy to detect and fix.

So I think I would still prefer the defconfigs to not enforce a C
library, and use the default of Buildroot, which is now glibc.

Thanks!

Applied to next, thanks.
