absl::StrFormat() unconditionally includes <cwchar>. So a toolchain
with wchar support is required.

This was introduced to abseil in [0] and landed in buildroot with the
bump to 20240722.0.

[0] https://github.com/abseil/abseil-cpp/commit/5dc2cc1a6a992e09d9cf930cdce7984640e2b7e0

Fixes:
https://autobuild.buildroot.org/results/948/948463b01ce52456179b06ae17d4ace9a823f92b//

Fixes: 0d40b47866 ("package/libabseil-cpp: bump to version 20240722.0")
Assisted-by: Github Copilot:GPT-6 Luna
Signed-off-by: Michael Nosthoff <buildroot@heine.tech>

---

V3: add Fixes with commit that introduced the issue to buildroot.

V2: - moved the depends from ARCH_SUPPORT directly on the symbol.
 - propagate that dependency to packages
 - update comment
