[Buildroot] [PATCH] package/libabseil-cpp: require wchar

[Michael Nosthoff via buildroot]

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

Fixes:

New dependencies must propagate to all reverse dependencies,
recursively.

Also, dependencies comment below needs update.
